How to manage Instagram analytics data for  multiple client accounts.

hi Smith456​  This usually happens because Instagram/exported CSV files use a different date format than your Excel regional settings.

A few things that normally fix it:

• Import the CSV using Data → From Text/CSV instead of opening it directly
• In the import preview, select the date column and set the correct Data Type = Date
• Choose the right format (MDY, DMY, etc.) before loading the data

If the dates are already imported incorrectly:

Select the column

Go to Data → Text to Columns

Choose Date and pick the correct format

Once Excel recognizes them as real dates (not text), your pivot tables and grouping should work correctly.

Also worth checking for:

Hidden spaces

Mixed date formats

Timestamps coming from Instagram exports

Those can also break pivots/grouping.
