Upload problems are usually about the file, not the app. Format mismatch, a schema that’s out of date with the source, or an encoding issue that slipped through — these checks cover the most common causes. Work through them before re-exporting or changing the schema.

​
Symptoms

  • Upload does not start.
  • Upload completes but parsing fails.
  • Fields appear shifted or missing.
  • A run completes with unexpected zero matches. (If the file uploaded cleanly but the run shows zero matches, see Reconciliation runs for join-key and business-period checks.)

​
Checks

  1. Open Ask Darpan and search for the official surface where the upload failed: Create Schema or Run Reconciliation.
  2. Confirm the file format matches the selected workflow.
  3. Confirm the schema matches the input headers or keys.
  4. Check encoding and delimiter.
  5. Remove blank leading rows and summary footer rows.
  6. Confirm identifiers have not been converted to numbers by a spreadsheet tool.

​
Common fixes

  • Save CSV files as UTF-8.
  • Preserve leading zeros in identifier columns.
  • Normalize date formats before upload.
  • Use a schema that matches the current source shape.
