what the import can read
- CSV (comma or semicolon) and Excel (XLSX) files, up to 20,000 rows.
- Contact cards (vCard) for contacts.
- Headers in French or English: columns are matched for you.
- Nothing is written to your account until the import is launched.
- The file is read, kept only while the import runs, then deleted.
What doesn't come over on its own: measurement history, progress photos and old messages. We look at what your app lets you export, together.
