Troubleshooting

Use this page when Bulk Fill does not behave the way you expect. Start with the symptom that best matches what you see, then work through the likely causes and fixes.

PDF Uploads But Cannot Be Used​

Symptom​

The PDF does not open cleanly, or Bulk Fill blocks you before mapping starts.

Likely Causes​

  • The PDF is password-protected.
  • The file is too large for the current upload limit.
  • The PDF uses structures the editor cannot process reliably.

How To Fix It​

  1. If the file is locked, remove the password and upload the unlocked copy.
  2. If the file is too large, compress it or simplify the source PDF before uploading again.
  3. If the file is incompatible, re-save it as a new PDF and retry.

CSV Upload Fails Or Looks Wrong​

Symptom​

Bulk Fill reports a CSV error, shows no rows, or the column list does not match what you expected.

Likely Causes​

  • The file is not a valid CSV.
  • The file is empty or only contains blank rows.
  • The separator or encoding came out wrong during export from another tool.
  • You expected the first row to become headers automatically.

How To Fix It​

  1. Re-save the file as a standard UTF-8 CSV.
  2. Remove empty trailing rows and unused columns.
  3. Re-open the file and confirm the values are separated consistently.
  4. Remember that Bulk Fill treats every row as data. If your file includes a header row, it will appear as row 1 and must be excluded during export.

Mapped Results Are Blank​

Symptom​

The PDF shows empty output where a mapped field should appear.

Likely Causes​

  • The field is not mapped.
  • The field is mapped to the wrong column.
  • The CSV cell for that row is empty.
  • The upstream CSV changed column order after you mapped the layout.

How To Fix It​

  1. Open the Fields tab and confirm every field is mapped.
  2. Preview the exact row that looks wrong and inspect the corresponding CSV value in the Data tab.
  3. If the column order changed, remap the affected fields before exporting.

Output Is In The Wrong Place​

Symptom​

The value is filled, but it lands in the wrong part of the page.

Likely Causes​

  • The field overlay was placed in the wrong position.
  • The source PDF layout changed after the fields were placed.
  • The mapped content is longer than the space available.

How To Fix It​

  1. Go back to the editor and move the field overlay.
  2. Preview several rows, not just one short sample row.
  3. If the layout changed, re-check all field placements before exporting.

Text Is Cut Off Or Overflows​

Symptom​

The exported text is truncated, crowded, or spills into nearby content.

Likely Causes​

  • The field area is too small for the data.
  • Some rows contain unusually long values.
  • The layout leaves too little room for variable-length text.

How To Fix It​

  1. Increase the available space in the layout or move the field.
  2. Preview the longest expected values before running the batch.
  3. Shorten or normalize the source data where possible.

Some Rows Look Wrong But Others Look Fine​

Symptom​

Only a subset of rows fail, while the rest of the batch looks normal.

Likely Causes​

  • Some rows contain blanks, long values, or unexpected formatting.
  • Row 1 is a header row that you forgot to exclude.
  • The rows you tested in preview were not representative.

How To Fix It​

  1. Use the row controls to inspect the failing rows directly.
  2. If row 1 is a header row, start the batch range at row 2.
  3. Compare the failing rows against a working row and fix the source data.

Preview Looks Fine But Export Does Not​

Symptom​

The preview looked correct, but the downloaded result is still wrong.

Likely Causes​

  • You previewed only one safe row and skipped edge cases.
  • The export range included rows you did not validate.
  • The batch output was larger or messier than expected.

How To Fix It​

  1. Export a preview PDF again for one problematic row.
  2. Re-run the batch with a smaller range to isolate the issue.
  3. Re-check the export options before retrying.

File Or Batch Size Problems​

Symptom​

Bulk Fill blocks the upload, refuses the batch, or tells you the output is too large.

Likely Causes​

  • The PDF is larger than the current upload limit.
  • The batch output is too large for the selected delivery path.
  • The current plan does not allow the export you attempted.

How To Fix It​

  1. Reduce the source PDF size if possible.
  2. Export a smaller range first to confirm the layout works.
  3. Check whether your current plan and usage still cover the export.
