Sejda is one of the most-searched PDF to Excel converters online, and for good reason — it generally produces decent results for simple tables. But if you've used the free tier, you've experienced the frustration:
- 3 tasks per hour — convert 3 files and you're locked out for 60 minutes
- 50 MB limit — financial reports and data exports often exceed this
- 200 page limit — long reports get truncated
- $7.50/month to remove these limits ($63/year billed annually)
More critically, Sejda's table detection struggles with:
- PDFs with multiple tables on one page
- Tables that span across pages
- Merged cells and complex headers
- Tables without visible borders
- Scanned documents (requires OCR)
If you convert PDFs to Excel regularly — for financial analysis, data extraction, report processing — there are better options. Let's compare.

Where Table Extraction Goes Wrong (and How AI Fixes It)
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:
Problem 1: Tables Without Clear Borders
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.
Problem 2: Multiple Tables on One Page
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.
Problem 3: Tables Spanning Multiple Pages
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.
Problem 4: Scanned PDFs
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.
Real-World Conversion Scenarios
Financial Statements
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
Bank Statements
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
Government/Tax Forms
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
