- Verify a cell by row, column and units before accepting a table extraction.
A rotated page can look readable while its table structure remains ambiguous. Instead of requesting every number immediately, ask Argon to identify orientation and name a target cell by both row and column. This makes a useful small check before extracting a larger table from an image or PDF.
Argon access is documented in AI Studio and the API; do not assume the Gemini consumer app or a free account provides it. You can practise the technique on the supplied fictional inputs with an available compatible assistant first. This lesson is documentation-based; examples are expected results, not a claim that we ran the named model.
Before you start
- A permitted table image or PDF with its complete headers visible.
- Two target cells you can read directly and use as known checks.
Bring your own attachment
Attach the original table image or PDF, keeping column headings, row labels, footnotes and units. If necessary add a separately rotated readable copy.

Documentation-based review · 2026-10-18
Provider documentation checked on 18 October 2026. Examples and checks are original illustrative exercises, not recorded platform tests. Cover artwork is conceptual and does not imply provider sponsorship.
Preserve the table frame
Keep the complete row labels, headers and units visible. Provide the original and a corrected-orientation copy if you can make one without losing detail. Do not crop a currency symbol or “per month” note away from the numeric cells.
Example / expected result
Illustrative example; not a recorded model result.
Fictional table: rows Basic/Plus; columns Monthly/Annual. Basic Monthly=USD 12; Basic Annual=USD 120.
Check your result
Both target cells can be located using visible row and column labels.
Ask for header-first extraction
Request the orientation and header mapping before values. For each target, require row label, column label, units, value and uncertainty. If a heading cannot be read, stop that cell instead of guessing its position.
Inspect the attached table. First identify readable orientation, rows, columns and units. Then extract only Basic × Monthly and Basic × Annual. Return each full row/column anchor and uncertainty. Do not infer missing headers or normalize annual prices into monthly prices.Example / expected result
Illustrative example; not a recorded model result.
Basic | Monthly | USD/month | 12. Basic | Annual | USD/year | 120. These are different billing periods, not a conflict.
Check your result
The answer does not place USD 120 in Basic Monthly.
Compare the anchors directly
Reopen the source and trace each value across its row and down its column. Only after those known checks pass should you request more cells. Retain uncertain footnotes or merged headers as separate review items.
Check your result
Each accepted value points to the correct row, column and billing unit in the source.
When it goes wrong
Merged headers, footnotes and multi-page tables can change the meaning of a cell. Rotating an image does not restore detail lost through blur. Ask for a better source instead of accepting confident positional guesses.
Make it your own
Swap the column order in a new fictional table while retaining the same headings. Check that the assistant follows labels rather than reusing the earlier left-to-right arrangement.
