Solving Common Problems with Shared Excel Files

Sharing Excel files is pretty common in most organizations, allowing teammates to have access to specific files and make necessary changes aligned with their responsibilities. This is possible through Excel online (web-based version of Excel) which boosts productivity and fosters teamwork. However, the convenience of shared Excel files is sometimes tied to various challenges and issues that need careful consideration. You may constantly receive vague errors and deal with problems regarding permissions, security, compatibility and so on. In this blog post, we’ll walk through common problems with shared Excel files in professional settings and provide you with the most practical solutions to be applied for each.

Understanding the Common Problems

When it comes to Excel file collaboration, a broad range of challenges can occur, from version conflicts to data integrity issues and access problems. Recognizing and addressing these common problems with shared Excel files is crucial for maintaining a smooth and effective collaborative workflow. Let’s dive in and see what exactly these challenges are.

Problem 1: Excel Version Conflicts

One of the most prevalent issues in shared Excel file collaboration is version conflicts which happen when there are multiple versions of the same Excel file with different changes made by different users. This is likely to happen in three situations:

• Simultaneous Editing: When two or more users open the same Excel file and make changes simultaneously, the system has to decide how to merge these changes. If the changes overlap or conflict, a version conflict arises.
• Offline Editing: A user may work on a local copy of the Excel file while disconnected from the network, and later attempts to sync changes. Conflicts may occur if other users have modified the online version during this time.
• Delayed Updates: When users do not regularly save and sync their changes, or if there are delays in syncing, it is likely to have version conflicts as different users work on outdated copies.

Fortunately, there are multiple solutions for Excel file sharing to address these challenges and avoid version conflicts:

Cloud-Based Storage

You can host your Excel file in cloud-based storage solutions such as Microsoft OneDrive, Google Drive, or Dropbox and share it with others. These platforms enable real-time collaboration, allowing multiple users to work on the same workbook simultaneously with co-authoring. Changes are synced instantly, and version history is maintained automatically, reducing the chance of version conflicts.

Version Control

Version control features in Excel or third-party systems are beneficial to address version conflicts. This tool tracks changes made by different users, making it easier to merge modifications and resolve conflicts. Some version control systems offer a check-out system, where users must check out a file before making changes to prevent simultaneous editing and reduce the likelihood of conflicts.

Communication and Coordination

Establish clear communication channels within your team, inform team members when you are working on a specific file, and encourage them to do the same. These communications minimize the chance of multiple users making changes simultaneously. You can also establish a schedule or use notifications to prompt users to sync their edits, reducing the likelihood for conflicts to arise.

Merge Tools and Conflict Resolution

Some version control systems offer automated merge tools that attempt to adjust conflicting changes intelligently. These tools can be particularly useful in complex collaborative scenarios. In cases where conflicts cannot be automatically resolved, provide a procedure for manual conflict resolution. This involves reviewing conflicting changes and deciding which modifications should be kept.

You can also merge different copies of a shared workbook by adding the “Compare and Merge Workbooks” feature to your Excel quick access toolbar. Using this feature, you can select all the copies you want to merge and have all the changes made by different users in one single workbook.

Recent Changes Priority

In some cases, you may need to keep the latest version of a document and prioritize recent changes to others without any conflict. To do so, you can follow these steps:

1. Navigate to the “Review” tab, “Changes” group, and click “Share Workbook”.

Go to the “Advanced” tab. In the “Conflicting changes between users” section, , select The changes being saved win, and click “OK”.

Problem 2: Data Integrity Issues

Issues regarding data integrity in Excel are among common problems with shared Excel files that can pose a significant risk to the accuracy and reliability of your information. These problems arise due to the collaborative nature of Excel work, and two common ones include “Accidental Data Overwrites” and “Data Inconsistencies”:

Accidental Data Overwrites

Accidental data overwrites occur when two or more users try to edit the same cell or range of cells simultaneously. Without proper controls, the changes made by one user may overwrite or replace the changes made by another one, leading to the loss of information.

 Data Inconsistencies

Data inconsistencies take place when different users enter conflicting information or make contradictory changes in the spreadsheet. For instance, one user may update a total in one part of the document while another user modifies a related value elsewhere, creating inconsistencies that impact the overall accuracy.

To minimize the negative impact of data inconsistencies, you can take advantage of 5 different solutions:

Cell Protection

To prevent accidental overwrites, consider locking cells which contain crucial formulas, constants, or reference data that should not be modified frequently. Excel’s cell protection settings also allow you to restrict editing access to specific cells or ranges. By assigning passwords or using user-level permissions, you can control who can make changes to protected cells. To access protection settings in Excel, navigate to the “Review” tab and “Changes” section. For instance,  click on “Protect Sheet” to set a password and allow users to make certain changes in a specific sheet.

Shared Workbooks

Excel offers a “Shared Workbook” feature that allows multiple users to edit the same workbook simultaneously. Enable this feature to leverage real-time collaboration and minimize the risk of data integrity issues.

However, you cannot access many Excel features such as Sorting and Filtering, Conditional Formatting, Charts and Pictures, Data Validation, etc. when activating shared workbooks. Thus, be sure to apply these features before sharing the workbook as the applied features can be used after the workbook is shared.

You can also activate the “Track Changes” feature within a shared workbook to monitor modifications made by different users. This tool helps identify changes and address common problems with shared Excel files, reducing the likelihood of data inconsistencies.

Data Validation

Implement data validation rules to define acceptable data ranges and formats, ensuring that users enter accurate and consistent data. Dropdown lists are also applicable for fields with predefined options. Using them not only guides users in entering accurate information but also standardizes data, minimizing inconsistencies in your sheets.

Collaboration Platforms

Don’t miss collaboration platforms like Microsoft Teams or SharePoint that offer advanced version control and data management features. They can provide enhanced tools for collaborative Excel work and allow you to store Excel files in a centralized location, managing access permissions and reducing the risk of unauthorized edits.

Regular Backups

Establish a routine for automated backups of shared Excel files. In case of accidental data overwrites or inconsistencies, having recent backups allows for quick data restoration. Take advantage of Excel’s version history or use external backup systems to keep track of changes over time.

Problem 3: Access and Permissions Challenges

Access and permission issues can be common problems with Excel-shared files, impacting the ability of team members to work seamlessly on documents. File locking and access restrictions are key concerns that can affect the collaborative process.

File Locking

File locking occurs when one user opens a shared Excel file, and other users are restricted from making edits until the file is closed. While this mechanism prevents simultaneous editing, it can lead to delays and conflicts if users are unaware that someone else is working on the file.

Access Restrictions

Access restrictions involve limitations on who can view, edit, or share a particular Excel file. It’s crucial to balance access control to prevent unauthorized modifications while allowing the necessary level of access for collaboration. 

Solutions for managing Access and Permissions in Excel are explained below:

Shared Drives

Aside from version conflicts, cloud-based storage solutions can also be used for addressing access restrictions. You can use them to centralize Excel files and ensure that team members access files from a common location, reducing the likelihood of access issues.

Document Check-Out System

As we mentioned earlier, checking out a file before making edits can prevent simultaneous editing and probable conflicts. When a user checks out a file, others can still view it but not make changes until it’s checked back in. You can use notifications to inform team members when a file is checked out or checked back in.

User-Level Permissions

Define proper roles for the users and assign permissions based on these roles. This helps maintain a balance between collaboration and data security. To add an extra layer of security, consider password-protecting sensitive Excel files, ensuring that only authorized users can access and modify the file.

Regular Access Audits

Conduct regular audits of access permissions to ensure they align with the current team structure and project requirements. Remove access for users who no longer require it. Try cleaning up the workbook by removing inactive users and clearing all the custom views, regularly. To remove inactive users, follow the steps below:

1. Go to the Review tab from the ribbon.
2. Select the Share Workbook option in the Changes group.
3. In the Share Workbook dialogue box, go to the Editing tab.
4. In the “Who has this workbook open now.”, select the user you want to remove.
5. Click on the Remove user button and press OK.

You can also write a macro that automatically removes inactive users from a shared Excel file. A custom macro can ask users every few hours if they are active. If no response is received, then the inactive user is removed.

Problem 4: File Size and Performance Concerns

Large file sizes in Excel can lead to performance degradation, slowing down operations and impeding the collaborative experience. These are common problems with shared Excel files related to large file sizes:

• Increased Load Times: Opening and saving large Excel files can take longer, especially when multiple users may be accessing the file simultaneously.
• Performance Lag: As the file size grows, users may experience lag and delays when navigating through the spreadsheet, entering data, or performing calculations.
• Compatibility Challenges: Large files can pose compatibility issues, especially when sharing among users with different versions of Excel.

Here are some tips for optimizing file size and improving performance:

Remove Unused Cells and Worksheets

Eliminate empty rows and columns that are not in use as they contribute to file size. If certain worksheets are no longer necessary, consider deleting them too. This reduces the overall size of the Excel file.

Use Data Consolidation

Instead of spreading data across multiple sheets, consolidate similar data into a single worksheet. This minimizes the number of sheets and assists you in file size optimization. You can also utilize PivotTables to summarize and aggregate large datasets, making data more manageable.

Optimize Formulas and Calculations

Use efficient formulas that perform the same task with less computational loading. For example, use SUMIFS instead of multiple SUMIFs. You should also try to minimize the use of volatile functions like OFFSET and INDIRECT, as they recalculate every time any change occurs in the workbook, impacting worksheet performance.

Data Compression Techniques

If the Excel file contains images, compress them to reduce file size. You can use image editing tools to adjust resolution and size of images before inserting them into the spreadsheet. Removing excessive styling and conditional formatting that may contribute to file bloat is also effective in boosting performance.

 External Data Sources and PivotCache

Link Excel to external data sources rather than embedding the data. This reduces the file size and ensures that the most up-to-date information is accessible. When using PivotTables, optimize the PivotCache to reduce redundant data storage and enhance performance.

Split Large Files into Smaller Ones

If possible, split large datasets into smaller files based on categories or time periods. This can improve performance and make individual files more manageable. You’d better link data between different Excel files rather than consolidating everything into one large file. This reduces the size of each individual file.

Upgrade Hardware and Software

If you constantly work with extremely large datasets, use the 64-bit version of Excel, which can handle larger file sizes more efficiently. Moreover, consider upgrading computer hardware, especially RAM, to improve overall performance when working with large files.

Real-Time Collaboration

Traditional communication methods, such as emails or messaging apps, may introduce delays in conveying important information or feedback, affecting the real-time collaborative experience.

Here are some effective solutions for streamlining communication among team members:

Comments and Annotations

You can use the commenting system in Excel to add comments to specific cells and provide context for changes. This ensures that collaborators fully understand the purpose behind any modification. Beyond basic comments, consider using annotations or text boxes for more extensive explanations.

Online Collaboration Tools

The Aforementioned collaboration platforms offer real-time collaboration features, allowing team members to work on the same Excel file simultaneously and communicate within the platform. Don’t miss chat functionalities and discussion threads within these platforms to facilitate real-time communication. 

Visual Indicators

Use cell highlighting to visually indicate changes made by different users. This provides a quick way for collaborators to identify modified cells and understand the changes. Conditional formatting is also helpful for automatically highlighting cells or ranges that have been recently modified. This simplifies the process of identifying changes. You can access conditional formatting through the Home tab> Styles> Conditional Formatting.

Collaborative Editing Features

Leverage collaborative editing features available in Excel Online or cloud-based platforms, allowing multiple users to work on the same document simultaneously. Many collaboration platforms display live presence indicators, showing which users are currently active in the document.

Scheduled Check-Ins

Schedule regular team meetings or check-ins to discuss ongoing Excel projects. This facilitates direct communication, allowing team members to ensure everyone is on the same page.
