More critically, Sejda's table detection struggles with:

The #1 complaint about PDF to Excel conversion — across all tools, not just Sejda — is accuracy. The output often requires significant manual cleanup. Here's why, and how AI-powered extraction changes the game:
Many professional documents use alternating row colors or whitespace instead of grid lines. Traditional converters (including Sejda) look for lines and borders. No borders = no detected table.
AI approach: ZiaSign's converter uses machine learning trained on millions of document layouts to identify table structures from visual patterns — spacing, alignment, font changes, and repeating data patterns — even without borders.
A financial report might have a revenue table, an expense table, and a summary table all on page 3. Many converters merge them into one confused spreadsheet.
AI approach: ZiaSign detects individual table boundaries and creates separate sheets or clearly separated sections in the output.
A 50-row table that flows from page 2 to page 3 might be split into two disconnected tables, with repeated headers.
AI approach: ZiaSign recognizes continued tables and merges them correctly, removing duplicate headers.
Scanned documents are images — there's no text data to extract. Without OCR, conversion is impossible.
ZiaSign advantage: Free OCR support. Sejda charges for OCR on their Pro plan.
Challenge: Multiple tables, merged header cells, footnotes mixed with table data
Result with Sejda: Headers often misaligned, footnotes inserted into data rows, merged cells lost their spanning
Result with ZiaSign: Clean separation of tables, proper header hierarchy, footnotes excluded from table data
Challenge: Transaction tables spanning many pages, running totals, date formatting
Result with Sejda: Running totals sometimes treated as data rows, date formats inconsistent, tables split at page breaks
Result with ZiaSign: Continuous table across pages, correct date formatting, running totals properly handled
Challenge: Complex layouts mixing form fields with tabular data, checkboxes, multi-column layouts
Result with Sejda: Form fields and tables merged, layout confusion, poor column alignment
Result with ZiaSign: Tabular data extracted cleanly, form field data preserved separately
