Fix a messy Excel export without retyping a cell

Stray spaces, blank rows, the same claim entered twice, dates in five formats and “RM 1,250.00” stuck as text. Drop the file in, choose what to fix, and get a clean sheet with a log of every change.

Cleaning rules

Drag an .xlsx, .xls or .csv file onto this card. Switch off anything you want left as it is.

Dates in my file are written

It cleans the mess, not your data

Three rules keep the values that matter exactly as they were.

01

Leading zeros stay

Phone numbers, staff IDs and account numbers stay as text, so 0123 never turns into 123 and a long account number never turns into 1.2E+12.

Dates follow your order

Tell it how your team writes dates. A date that cannot exist, like month 31, is left alone instead of guessed.
