Step 1 of 4
Upload your source file
CSV, TSV, XLSX, or XLSM, up to 25 MB. The file is parsed by the backend and the original bytes are stored, so a repair can always return to the source.
One source file per migration. Keeping them separate is what makes execution, verification, evidence and rollback isolated and auditable: every row committed can be traced to one upload, and rolling back removes exactly those rows.
