Quick answer
For Table OCR, follow a checklist: backup, format, size/quality, output, spot-check. Table OCR easily misaligns columns; crop single tables/rows first.
Why it matters
A fixed checklist prevents skipping the critical step.
Merged cells are more error-prone.
Step by step
- Check for a text layer: if text is selectable/copyable, OCR may be unnecessary.
- For scans, raise resolution/contrast and deskew.
- Pick the right language (Chinese/English/mixed) and only the needed pages.
- Proofread numbers/amounts/dates/names; don't trust OCR blindly.
- Export TXT/copy, keep the original PDF and a proofreading record.
Common mistakes
- OCR-ing a PDF that already has a text layer and adding errors.
- Low-resolution/skewed scans producing poor accuracy.
- Using one language for mixed Chinese/English pages.
- Not proofreading amounts/dates/IDs before importing.
Checklist
- Text layer vs scan determined.
- Resolution/orientation/contrast handled.
- Language/page range chosen correctly.
- Numbers/amounts/dates/names proofread.
- Original PDF/proofreading record kept.
Key facts
- Merged cells are more error-prone.
