How it works

  • Nested objects become columns like vendor.taxId.
  • Columns are the union of all record keys, in first-seen order.
  • Finds the record list inside wrapper objects such as { "data": [...] }.

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.
