More reliable PDF-to-Excel conversion and OCR processing

Large PDF files convert to Excel more reliably, and OCR retries no longer leave files in a broken state.

Improvements

  • PDF to Excel on large documents: The extraction pipeline that cleans and fills converted tables now processes pages in batches. Large PDFs that previously failed mid-conversion due to size limits will complete successfully. Pages that are exceptionally large are escalated to a higher-capacity model; pages that still exceed limits are skipped gracefully rather than aborting the entire conversion.

Bug Fixes

  • OCR retry reliability: If an OCR job had to retry after partially completing, subsequent attempts could fail with a conflict error — leaving the file stuck in a failed state. Retries now cleanly replace any partial results, so files recover correctly without manual intervention.
