Table OCR
Table OCR for rows, columns, and multi-page data
Recover the grid the reader can see, even when the file stores only pixels or scattered text.
Table OCR has two jobs. It must read each character and infer the cell structure around it. A transcript can recognize every word and still be useless if values drift into the wrong columns.
Borderless tables, wrapped descriptions, merged headings, blank cells, and repeated headers need layout reasoning. The output should preserve row order and make uncertain cell boundaries easy to inspect.
Where table ocr fits
- PDF tables that copy and paste badly
- Scanned schedules and statements
- Screenshots or images of tabular data
How table ocr works
- Locate table regions: Separate grids and aligned value blocks from surrounding titles, notes, and page furniture.
- Infer columns and headers: Use borders, whitespace, alignment, and repeated value patterns to define the grid.
- Build rows: Keep wrapped text, blank cells, subtotals, and continuation pages attached to the right records.
- Validate the dataset: Check column types, row counts, totals, and page transitions before export.
What the structured result can contain
| Field or structure | Example |
|---|
| Table title | Transaction detail |
| Column headers | Date, description, debit, credit |
| Rows | 2026-08-28, Transfer, 420.00, blank |
| Cell confidence | Review amount in row 18 |
| Source page | Page 3 |
A complete-looking table can still be wrong
Structural errors are dangerous because every cell may contain plausible text while the row or column assignment is incorrect.
- Compare extracted and source row counts.
- Check blank cells instead of shifting later values left.
- Remove repeated page headers without dropping real rows.
- Review merged cells, grouped headers, and footnotes.
- Recalculate totals and check numeric columns for date or currency coercion.
OCR API response design
Return tables as arrays of typed rows plus the original header labels and source coordinates.
Support multiple tables per page and do not force unrelated grids into one schema.
Read the document extraction API guide.
Common uses
PDF to Excel
Move report tables into a workbook without rebuilding rows by hand.
Statement extraction
Recover transaction grids and preserve amounts, signs, and balances.
Data migration
Convert scanned schedules into structured records with a review trail.

Table OCR questions
Can OCR extract a table without grid lines?
Yes. Alignment, spacing, headers, and repeated data types can reveal columns, but borderless tables usually need closer review.
Can table OCR join rows across pages?
It can identify repeated headers and continued structures. Carried totals and page notes should be excluded with explicit validation.
Which export format is best?
Use CSV for one flat table, Excel for several tables or manual review, and JSON when nested structure or API delivery matters.
