Problem with data grouping in Excel

Copper Contributor

Hi everyone, 

Today, while working on my excel sheet, I faced a problem. Indeed, I have an Excel spreadsheet which works very well now. I have a sheet where I can create my groups of lines without any problem. However, I have another sheet in the same Excel spreadsheet or when I want to create a grouping of lines, nothing will happen, only a very thin gray bar will appear at the location of the grouping, without being able to do anything about it.

It seems like you are experiencing issues with data grouping in Excel, where the grouping lines do not appear or function as expected in one of your sheets. This issue can occur for various reasons, and I will provide some troubleshooting steps to help you resolve it:

  1. Check Worksheet Protection: Make sure that the worksheet where you are trying to create data groups is not protected. If it is protected, you will not be able to create or modify data groups. To unprotect a sheet, go to "Review" > "Unprotect Sheet" and enter the password if required.
  2. Verify Excel Version: Data grouping features can vary slightly between different versions of Excel. Ensure that you are using a version of Excel that supports data grouping.
  3. Data Format: Check the formatting of the data in the problematic sheet. Ensure that your data is in a tabular format with column headers and that there are no merged cells within the data range.
  4. Sort Data: Sometimes, data grouping may not work correctly if the data is not sorted. Try sorting your data based on the column you want to group by.
  5. Clear Filters: If there are filters applied to your data, clearing them might resolve the issue. Go to "Data" > "Clear" > "Clear Filters" to remove any filters that could interfere with grouping.
  6. Excel Add-ins: Some Excel add-ins can conflict with Excel's built-in features. Try disabling any add-ins you have installed and see if the grouping works as expected.
  7. Repair Excel Installation: If the issue persists, you can try repairing your Excel installation:
    • Close all Office applications.
    • Go to "Control Panel" > "Programs" > "Programs and Features."
    • Locate Microsoft Office, right-click it, and select "Change."
    • Choose "Repair" and follow the on-screen instructions.
  8. Create a New Worksheet: If none of the above steps work, you can try creating a new worksheet within the same workbook and see if grouping works correctly in the new sheet. If it does, you can consider moving your data to the new sheet.
  9. Update Excel: Ensure that you have the latest updates and patches installed for your version of Excel. Microsoft frequently releases updates to address bugs and improve stability.
  10. Use VBA Macros: If the issue persists and grouping is critical for your workbook, you can consider using VBA (Visual Basic for Applications) macros to create custom grouping functionality.

If none of these steps resolve the issue, there may be a specific issue related to your Excel file or installation. In such cases, it would be beneficial to have more information about the digital environment. Information such as Excel version, operating system, storage medium, etc.

This would lead to a more accurate and faster solution suggestion.

My Excel 365 (Both Personal and Business) doesn't support New Excel Functions: GROUPBY and PIVOTBY, could you please suggest how to resolve the issue? Thanks


That doesn't have to do anything with the subject of this discussion. But GROUPBY and PIVOTBY are currently only available to Microsoft 365 Insiders. They will probably be rolled out to regular users sometime during 2024.
