Prettify and minify JSON for reviews, diffs and checked-in fixtures
Readable JSON is how teams review API samples, debug webhook payloads and keep fixture files consistent in git. Minified JSON is what you paste into curl examples, log aggregators and size-sensitive configs. This formatter parses your text in the browser, then re-emits it with configurable indentation or as a single compact line. Nothing is uploaded to Datamata Studios for formatting, so you can prettify redacted production responses on a locked-down laptop without routing secrets through a third-party paste service.
Format workflow
- Paste raw JSON from logs, Postman or a migration script.
- Choose indent size for pretty output or switch to minify for transport.
- Copy the result into your PR, ticket or OpenAPI example block.
- Run the JSON Validator if the paste failed to parse before you blame formatting.
When pretty-print beats minify
Code review and pair debugging benefit from two-space or four-space indentation so nested objects line up with their parents. Minify when byte count matters in embedded configs or when you need a canonical single line before hashing. The formatter does not reorder keys arbitrarily beyond what the parser returns, so semantic comparisons in the JSON Diff tool stay trustworthy after you normalize whitespace here.
Pair with validation, diff and schema work
Treat formatted output as presentation, not proof of correctness. Validate syntax in the JSON Validator, compare environments in JSON Diff and codify expected shapes with the JSON Schema Generator once fixtures look stable. When tabular exports arrive as CSV, convert with the CSV ⇄ JSON Converter first, then format the tree so column names and nested rows are obvious in review.
Habits that keep repos clean
Format fixtures in CI with the same indent your team picks here so local and pipeline output match. Avoid checking in minified blobs beside pretty versions of the same object — pick one style per directory. Redact tokens and personal data before pasting production samples, even though processing stays local. For YAML-heavy repos, round-trip through the YAML ⇄ JSONYAML ⇄ JSON Converter only after the JSON side is validated so you do not prettify invalid structure.
Production minify and key ordering
Minified JSON is standard for API responses over the wire but painful in code review. Keep pretty-printed copies in git for human review and minify in build pipelines. Object key order may change after parse and stringify — if order is semantically meaningful, treat that as a design smell and use arrays of pairs instead.
