What to do
Correct obvious orientation and inspect skew when a table’s columns are difficult to follow. Preserve the original and work on a copy. After rotating, confirm the page is not clipped and that its reading order remains sensible.
A page turned 90 degrees and a slightly slanted page are different capture issues.
Two worked review cases
These cases are fictional teaching data, not measured extraction results. Use the source excerpts to practise deciding what belongs in the reviewed output.
| Case | Fictional source excerpt | Review decision |
|---|---|---|
| Sideways page | Invoice page is readable only after a 90-degree rotation | Rotate a copy and inspect all four edges. |
| Slanted table | Row baselines slope across the image | Deskew or rescan, then verify row alignment at both margins. |
Suggested review columns
| Column | Definition or instruction |
|---|---|
| Source page | Page identifier for the original scan. |
| Orientation correction | Rotation or deskew action recorded by the reviewer. |
| Post-correction check | Confirmation that text and margins remain complete. |
These are suggested staging-sheet columns. Printed facts can inform field descriptions in Parzable’s Schemas view; source references, review statuses, and decisions must be supplied by your own review process.
A practical review sequence
- Determine whether the issue is orientation, skew, or perspective distortion.
- Apply the correction to a copy using an approved document tool.
- Recheck source details and compare a small extraction before and after.
Errors to avoid
- Do not crop a page merely to make it look straight.
- Rotation does not fix blur, glare, or perspective distortion by itself.
Use the case worksheet with a small sample
Download this page’s worked-case worksheet. It contains the two fictional cases above and a blank row for your own review exercise. Keep any real source documents in your agreed storage process.
For the broader product workflow, see the related guide. Parzable accepts PDF/image inputs and downloads CSV. Suggested structures here are review targets; nested item rows, automatic approvals, and destination integrations are not guaranteed.
