How it works
- Duplicate or empty headers get safe, unique keys.
- Numbers are typed only when exact; IDs with leading zeros stay strings.
- Choose objects keyed by header, or plain arrays of rows.
Questions
Are my files uploaded?
No. This tool runs inside your browser on this device. ORDO's servers never receive the file, and the page's security policy blocks it from sending file data anywhere.
