Member data cleaner

Drop in your exported member list, review what looks personal, download a version that's safe to send.

This runs entirely in your browser. CSV files never leave this page at all. Excel files use a small, well-known code library (SheetJS) fetched once from a public library server purely to read the spreadsheet format. Either way, your member data itself is never uploaded or sent anywhere.

01

Add your file

Export your member list from your membership system first. CSV or Excel both work here, no need to convert anything. Then drop it in below.

Drop your CSV or Excel file here, or click to choose a file

.csv, .xlsx, or .xls

Nothing uploaded.
Ever.

02

Review your columns

We've flagged anything that looks like personal data and switched it off by default. Check every row yourself.

You decide what's
personal, not us.

03

Preview what gets sent

First five rows only. Anything switched off shows as redacted here, exactly as it will be removed from the download.

leaves, before it does.
