Why the Filter is not Working in Excel?
You can face the “filter is not working” issue if you are applying the filter on a protected worksheet or trying to find the data from a hidden row. Besides this, there could be many other reasons contributing to this issue, such as:
- The data you are trying to filter is in merged cells.
- The Excel file automatically selected the data up to the first empty cell, excluding the remaining rows.
- Grouped sheets in Excel file.
- Blank row in the Excel sheet.
- You are trying to apply a filter on an invalid data range.
- The workbooks in which you’re facing the filter issues are corrupted.
- You are specifying incorrect criteria in the filter columns.
Solutions to Resolve the Filter is not Working Issue in Excel
There might be two scenarios: the Excel filter option is disabled/grayed out or the filters fail to function properly. You can follow the given troubleshooting solutions to resolve the issue based on the scenario you’re facing.
Scenario 1 – Filter Option is Disabled or Grayed Out
Method 1: Check and Un-group the Worksheet
When you apply filters to a single sheet in a grouped set, Excel disables the filter option in other sheets within the group. You can check the grouped sheets and try ungrouping them to enable the filter option. Here’s how to do so:
- In the Excel file, go to the Group section.
- Right-click on the Ungroup Sheets.
Alternatively, you can press the Shift + Alt + Left keys to ungroup the sheets.
Method 2: Unprotect Worksheet
The “disabled Excel filter” issue can also occur if your worksheet is protected. You can unprotect the worksheet to enable the filter option. To do so, go to the Review tab and then select Unprotect Sheet.
Method 3: Check and Uninstall Excel Add-ins
Sometimes, the Excel filter gets disabled due to faulty or corrupted Excel add-ins. You can run the Excel in Safe mode to check whether the issue has occurred due to add-ins. To do this, type excel /safe in the Run window and click OK.
In safe mode, if you see the filter option, it indicates some problematic Excel add-ins were causing the issue. In such a case, you can check and uninstall the faulty Excel add-ins to fix the issue.
Scenario 2 – Filter is not Working
Method 1: Try Clearing Filters
Sometimes, the Excel filter fails to work correctly if some filters from the previous sessions are still active. In such a case, you can clear the applied filters. Follow the below steps:
- In Excel file, click Sort & Filter option.
- Select clear.
Method 2: Select Entire Data
The filter not working issue in Excel can occur when the range selected for filtering is incomplete or incorrect. You need to make sure that you’ve selected the entire data range in Excel. You can use the Ctrl+A keys to select the entire content in the worksheet.
Method 3: Check and Delete Blank Cells from the Table’s Columns
When you apply a filter to the data, Excel expects data to be in a continuous range. Excel filters do not consider the blank cells, thereby resulting in incorrect functioning of the filter. To resolve this issue, check and delete all blank cells. In case your Excel file is too large to delete the blank cells, then you can add a “Serial number” row as an alternative. Adding serial number row creates a data continuity, thus helping in fixing the filter-related issue.
Method 4: Unhide Hidden Rows and Columns
Hidden rows or columns in worksheets can also affect the filter functionality. You can check and unhide rows/columns to troubleshoot the issue. Here is how to do so:
- In the affected Excel file, go to Home.
