Excel Ageing Calculator

Operations and finance teams often need to know how old a date is — invoices, GRNs, or tickets. Excelify calculates ageing in days from a date column without formulas.

How ageing works

Upload an Excel or CSV file, choose the date column, and Excelify adds an Ageing (Days) column based on today's date.

Preview the result and download a workbook. Processing stays in your browser.
