Words belong to rows and columns. Illustrative workflow.

Recover the table a reader can see, even when the file stores only pixels or scattered words.

Table OCR must read the characters and rebuild the grid around them. A transcript can contain every word and still produce bad data when an amount slips into the next column or a wrapped description becomes another row.

Borderless tables, merged headings, blank cells and repeated page headers need layout context. The output should preserve row order, expose uncertain cell boundaries and keep each page available for comparison.

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
पंक्तियों	2026-08-28, Transfer, 420.00, blank
Cell confidence	Review amount in row 18
Source page	Page 3

A tidy table can still put values in the wrong place

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.

Test table OCR as a data-structure problem, not a transcription problem

Start by marking the expected table boundaries, header levels, row count, and value types on a representative sample. Then compare the exported dataset with that reference. Character accuracy alone will not catch a debit placed under credit, a wrapped description split into two records, or a subtotal imported as an ordinary transaction.

Multi-page tables need explicit continuation rules. Repeated headers and footers should disappear from the data, but page references should remain. A row split by a page break must be joined only when the layout and values support it. Carried balances, section labels, and notes need their own treatment so they do not silently become rows.

Before opening the file in Excel, validate columns by type and relationship. Dates should parse as dates, amounts should remain numeric, and identifiers should keep leading zeroes. Compare source and output row counts, recalculate totals, and inspect blank cells. These checks find structural mistakes that a visually tidy spreadsheet can conceal.

Decide how to represent complex headers before export. A two-level header may need flattened names such as current_period_debit and prior_period_debit for CSV, while Excel can preserve a more readable multi-row heading. JSON can retain nested groups, but downstream code still needs stable keys and documented null behavior.

Keep multiple detected tables separate unless they share the same columns and business meaning. A summary grid, transaction table, and footnote schedule on one page are not one dataset. Joining them because their borders touch creates rows that look valid but cannot be reconciled.

Test the final format in the system that will consume it. Excel users may need visible review columns and frozen headers. An API client needs stable keys, data types, source coordinates, and predictable errors. The correct grid is only useful when it survives the handoff.

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.

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?

Yes. Table OCR 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.

Can I extract tables from PDFs with Ollama?

Use the local Ollama extraction workflow with a model that can return structured rows. Check borderless columns, merged headers, wrapped descriptions and repeated headings across pages. Compare row counts and totals with the original PDF before exporting Excel, CSV or JSON.
