How to why excel dates don't sort correctly and how to fix them
- Step 1Upload the file with the unsortable date column — Drop the .xlsx or .csv containing dates stored as text.
- Step 2Run the Date Standardizer — Every parseable date string is converted to a true date value in your chosen output format.
- Step 3Sort in Excel and verify — Open the output file, sort the date column — dates now appear in correct chronological order.
Frequently asked questions
How do I tell if my dates are stored as text?+
True Excel dates right-align in cells by default; text dates left-align. Or check: if sorting produces alphabetical rather than chronological order, they're text.
Will the converted dates work with Excel date functions like DATEDIF and EDATE?+
Yes. Once converted to true date values, all Excel date functions (DATEDIF, EDATE, NETWORKDAYS, etc.) work correctly.
What if only some cells in the date column are text while others are true dates?+
The tool converts every parseable text-stored date. True-date cells are passed through unchanged.
