1. Inspect the source and the intended columns
The source is a CC0 synthetic fixture generated by ParseMill for testing. It contains no customer data and is not a real supplier certificate. Both pages repeat the exact headers Sample, Test, Result, Unit, Method.
2. Inspect the extracted register
Five data rows, two source pages. Values below are the raw extracted strings. The source page numbers are displayed from 1; the downloadable JSON uses zero-based page indexes.
| Sample | Test | Result | Unit | Method | Source PDF | Review |
|---|---|---|---|---|---|---|
| S-001 | Tensile strength | 42.60 | MPa | ISO 527 | Page 1 | Unreviewed |
| S-001 | Elongation | 18.2 | % | ISO 527 | Page 1 | Unreviewed |
| S-002 | Moisture | < 0.0100 | % | ISO 15512 | Page 1 | Unreviewed |
| S-002 | Residue | 0 | mg | Internal | Page 2 | Unreviewed |
| 00042 | Density | 1,234 | g/cm3 | ISO 1183 | Page 2 | Needs interpretation |
How to check a source reference
Open the page link on the Moisture row. Find Sample S-002 and read the Result and Unit cells together: < 0.0100 and %. Check the qualifier, all four decimal places and the column alignment. A link to the right page does not by itself prove the value was extracted correctly.
The signed-in workspace highlights individual source words. This precomputed example provides page links and the raw JSON evidence for inspection.
3. Review what the parser cannot decide
1,234 is preserved. The report deliberately leaves the comma’s meaning ambiguous. The parser marks numeric interpretation unsupported; it does not choose between 1.234 and 1234.The other rows also remain unreviewed. Compare the moisture qualifier < 0.0100, explicit residue value 0, leading-zero identifier 00042, and units with the PDF. Source-page links locate the page; they are not an approval of the result.
The signed-in workspace offers cell-level source highlights and saved corrections. This public example uses a static table and source-page links, so it can be inspected before registration.
4. Download the precomputed output
The workbook contains Data, Sources and Exceptions sheets. Public sample source links are adapted to the downloadable fixture PDF; private workspace exports require access to their original source. All values are still unreviewed. CSV import can change numeric-looking identifiers, so verify 00042 after opening it.
5. Use the workflow for your own document
Invited users can open a workspace prefilled with these five column names, add a suitable PDF, review the result and export it. A new document is a new extraction and needs its own checks. Save the columns if you process more reports with the same layout.
Processing requires an invited account and an active allowance. Files may be up to 20 MB and 300 pages. If you do not yet have access, request an invitation; a request does not create an account.
