Published 2026-05-03

Snapshot testing
Parse PDF to JSON exports into fixtures, diff API payloads in CI — scrub PII before committing.
Schema drift
Let validation fail loudly when PDF layout changes — fix data, do not loosen schemas silently.
Also: Finance tables JSON/CSV.
Try PDF to JSON
Table extracts to JSON for fixtures, schema tests, and API parity checks.
Open ToolFrequently asked questions
Can JSON feed contract tests?
Yes — snapshot tabular payloads extracted from golden PDFs, then diff against API responses. Keep PDFs out of CI logs if they contain PII.
Schema validation?
Pipe JSON through ajv or pydantic after extraction; PDF layout drift will surface as validation errors — fix data, not the schema silently.
Nested tables?
Complex PDFs may flatten oddly. Split source PDFs per table region with [PDF Split](/tools/pdf-split) before extraction.
Compared to invoice posts?
Same [PDF to JSON](/tools/pdf-to-json) tool — this article focuses on API parity testing rather than AP postings.
