10 JSON jobs

Private JSON tools for everyday data work

Format, validate, compare, query, sort, escape, and convert JSON without uploading the document or creating an account.

Every operation works locally, even when telemetry is declined or blocked.

Choose a JSON job

Each route has its own inputs, limits, output, and guidance.

JSON FormatterTurn compact JSON into an indented document you can inspect, copy, or download without sending the payload away from your browser.Open tool
JSON ValidatorConfirm that a document follows strict JSON grammar and inspect a useful local diagnostic without transforming the source.Open tool
JSON MinifierRemove insignificant whitespace from valid JSON for a compact fixture, request example, or transport artifact while keeping values unchanged.Open tool
JSON Key SorterCreate a predictable object-member order for snapshots, reviews, and fixtures without changing arrays or evaluating the document.Open tool
JSON CompareFind meaningful structural changes between two valid JSON values while ignoring indentation and object member order.Open tool
JSONPath TesterSelect one or many nodes with child names, array indexes, and wildcards, then inspect normalized result paths in your browser.Open tool
JSON Pointer TesterFollow an RFC 6901 pointer from the root to one object member or array element and inspect the exact selected value.Open tool
JSON Schema ValidatorCheck types, required members, ranges, patterns, and other local JSON Schema constraints after both documents pass strict syntax parsing.Open tool
JSON String EscaperTurn plain text into a quoted JSON string literal, or decode exactly one valid literal back to its text value without evaluating code.Open tool
JSON to CSV ConverterCreate a spreadsheet-ready table from a non-empty array of flat records with deterministic headers and formula-safe text handling.Open tool

Start with the JSON formatter

The hub includes one immediately useful workspace. For schema, comparison, paths, pointers, string literals, or tabular output, choose the dedicated route above.

Format JSON

Inputs are limited to 1 MiB and stay in this browser tab.

Paste or edit the source. Tool Swim does not upload or save it.

Formatted JSON

Nothing is placed in a URL, account, or remote log.

A bounded local workspace

JSON often carries API credentials, user records, internal configuration, and debugging context. These tools parse and transform text in the active tab; the public experience has no upload endpoint, cloud save, or content-bearing telemetry event.

Inputs and generated outputs are capped at 1 MiB. Traversal depth and node count are bounded, remote JSON Schema references are disabled, and the JSONPath tester implements a documented non-evaluating subset. The limits make failure explicit instead of allowing unbounded browser work or hidden network resolution.

Local processing is not automatic redaction. Before sharing a copied result, remove secrets and personal data according to the destination's policy. When a stable machine contract matters, pair an interactive check here with validation in the system that actually consumes the payload.
