  • Sounds like you have a column of dates that are stored as text which you need to convert to numbers. Generally, this can be done with the =DATEVALUE() worksheet function, but that will fail on Jalali dates. There must be a way specify the date format that Excel should recognize, in this case [$-fa-IR,16]dd/mm/yyyy;@. I bet it's doable in PowerQuery.

  • @FarhoodNaqizade,, you mean to say after applying new date format,,, when you try PT and group on date, it doesn't works ?? If YES,,, then U need HELPER COLUMN,,, get either Year or Month or Even Date as Helper value and use that to GROUP data,, check formula below,,, #FlexYourData has shown !! Aug 23, 2020 at 5:14

For this I recommend just creating the columns with formulas. For example:

Then you can use those columns in the pivot table.
