The Excel Date Filter Is Not Grouping by Month – 3 Solutions

This is an overview.

The dataset showcases product code, selling date, and sales amount.

Solution 1 – If Dates Are Not in Proper Format

If the date is in Text format, it will be left aligned.

If you select more than one cell with dates, you will see only the cell count in the status bar.

If you add a filter to C4:C14, there is no month-based date filtering option.

If the inputs are in Date format, after applying the Filter month names will appear as a filtering option.

Solutions:

Convert the Date inputs into Date format.

• Select the cell range to filter. Here, C5:C14.
• Go to the Data tab and select Text to Columns in Data Tools.

• The Convert text to Columns Wizard will open.
• Select Delimited in Original data type.
• Click Next.

• Click Next.

• Select MDY date format in Column data format and click Finish.

Date format will be displayed and you will be able to Filter the dates by month.

Solution 2 – Not All Rows Are Selected When Grouping

In the image below only B4:D8 was selected while applying the Filter.

If you click the Drop-down beside Sales Date, you can only see March, April, and July as filtering options.

Solutions:

• Select the rows you want to filter. Here, B4:D15.
• Go to the Data tab and click Filter twice in Sort & Filter.

• Click the drop-down option, and you will be able to see all the months.
