Best Practices for PUB to SQL Conversion

  • →Before converting PUB to SQL, review the document structure — multi-column layouts, text boxes, and floating images behave differently across formats
  • →Export a PDF preview alongside the SQL file so you have a reference of how the document should look
  • →Check that hyperlinks and cross-references survived the PUB to SQL conversion — some formats handle links differently
  • →Run a spell check before conversion to avoid propagating errors into the final document
  • →Keep the original editable file in case the conversion introduces layout shifts
  • →Test the output on at least two different applications or devices

Troubleshooting PUB to SQL Conversion

  • !PUB to SQL formatting looks off → complex layouts with tables and columns may shift between formats
  • !Fonts render differently in SQL → embed fonts or use standard web-safe fonts before converting
  • !Images missing from the SQL output → ensure images are embedded in PUB, not linked externally
  • !Tracked changes disappeared after converting PUB to SQL → some document formats don't support revision tracking
