Anonymize a spreadsheet of real people
Upload a CSV or Excel file, tell it which columns hold personal details, and get back
two files: one with realistic fake data and one with the originals. Both share an
anon_key so the same person always maps the same way, and the tool proves
the pair can be merged back before you download.

Everything happens on your device. The file you choose is never sent anywhere.
No file of your own? Download a sample file to try it. It is made-up data, safe to experiment with.
Choose a sheet
This workbook has more than one sheet. Pick the one to anonymize.
Map your columns
Assign the personal-data columns to a common term. Only first name, last name, and date of birth are required. Everything else is optional. A full-name column can satisfy both first and last name. If your file has a customer or member number, map it to Record ID as well: it identifies a person better than a name and a birth date can.
