How it works

Upload one CSV. The AI reads a column profile and a few sample rows and proposes a cleaning plan from a fixed list of safe operations. The plan is then applied by code, so rows are never rewritten by the model. Every operation and its effect is listed in the report.

What you give it

.csv (comma-separated, UTF-8)

Limitations

Up to 50,000 rows, 100 columns, and about 1 MB of text.
Only the listed operations are available (rename, drop, trim, case, email, date, number, empty rows, duplicates).
Ambiguous dates (e.g. 03/04/2026) follow the date order in the plan; check the report.
Cells that start with =, +, - or @ are prefixed with ' in the output so spreadsheets don't run them as formulas.
