Clean JSON.
Zero noise.
Format, validate and inspect JSON — then move into dedicated tools for comparison, path exploration, schemas, TypeScript types, transforms, repair and Safe Share sanitization. PlovJSON runs entirely in your browser, with no adverts, no tracking and no unnecessary interface clutter.

A JSON workbench built for actual work.
Start with the fast Formatter, then move directly into dedicated local-first workspaces for comparison, paths, schemas, TypeScript, transforms, repair and sanitizing sensitive JSON before sharing.
Format & validate
Pretty-print JSON, validate syntax and get useful error feedback without uploading your payload.
Open Formatter →Fast formatter workflow
Minify, sort keys, open local files, copy results, download output and use keyboard shortcuts.
Open Formatter →Inspect as a tree
Switch from formatted text to a collapsible object and array tree when structure matters more than raw syntax.
Open Formatter →Compare JSON
Run structural JSON diffs, filter changes, inspect before/after values and export JSON Patch output.
Open Compare →Explore paths
Navigate JSON as a tree, generate exact JSONPath, JavaScript and JSON Pointer paths, and run local queries.
Open Paths →Infer schemas
Generate JSON Schema, validate payloads against supported schema rules and create example JSON locally.
Open Schema →Generate TypeScript
Infer interfaces or type aliases from JSON, including nested objects, arrays, unions and optional properties.
Open Types →Transform data
Flatten, unflatten, extract, rename and deduplicate JSON, plus convert between JSON and CSV.
Open Transform →Repair invalid JSON
Diagnose common syntax problems, preview deterministic fixes and explicitly apply a valid repaired result.
Open Repair →Sanitize before sharing
Detect common credentials and personal identifiers, review every finding, then create a safer redacted or anonymized copy without uploading your JSON.
Open Safe Share →Your JSON stays with you.
Formatting and validation happen in browser JavaScript. PlovJSON does not need an API, database or server-side JSON processor to do its job.
