Minified JSON is unreadable. One click formats it. All client-side.
JSON (JavaScript Object Notation) is the most widely used data exchange format on the web. REST APIs, configuration files, NoSQL databases, webhooks — they all speak JSON. The problem: JSON is usually minified (without spaces/line breaks) during transmission to save bandwidth.
With one click on "Format", your minified JSON is transformed into a clean, indented tree structure. Nested objects and arrays become visually recognizable, key-value pairs are instantly graspable.
The reverse path: formatted JSON from your development environment is compressed to a single line with "Minify" — ready for production. The minifier removes all non-functional whitespace and reduces file size by up to 40%.
Our formatter validates your JSON in real time as you type. Errors like missing commas, unexpected tokens, or improperly nested brackets are reported instantly with the exact position. All processing happens client-side in your browser — no JSON leaves your machine.
You just copied an API response from the terminal, curl, or Postman — a single 10 KB line without any structure. Or your config file is broken and you cannot find the spot. That is exactly what this formatter is for: minified JSON in, formatted tree out, errors flagged live. Everything stays in your browser — your JSON goes nowhere.
Paste the response from curl, Postman, or the network tab of the browser dev tools into the left field.
Click “Format” — the line-worm becomes a cleanly indented structure, nested objects and arrays visible at a glance.
If the JSON is invalid, the formatter highlights the error location live — you immediately see where the comma is missing or the bracket does not close.
Both buttons do the same format — just in opposite directions. Formatting produces the readable, indented representation for humans: ideal when debugging, inspecting webhook payloads, or understanding unfamiliar configs. Minifying removes all unnecessary whitespace and squeezes the JSON onto one line: one line instead of a hundred. That saves bandwidth and is the format APIs and servers expect. Rule of thumb: format to read, minify to transmit.
JSON Lines (NDJSON, newline-delimited JSON) is not one JSON document but many: one line, one JSON object — per line. Log files, streaming APIs, and data pipelines love NDJSON because every line can be processed independently. Our formatter helps here too: copy individual lines in and get them formatted and validated — instead of searching a huge file for the broken entry.
The most common causes: a trailing comma after the last element, duplicate keys in the same object, or a forgotten quote around a key. The validator shows you the exact position — no more searching through a hundred lines.
YAML is more human-readable (no brackets, fewer commas) and popular for config files. JSON, by contrast, is the API standard: every programming language has built-in JSON support, and JSON cannot break through an indentation mistake. There are plenty of conversion tools — but always validate the result.
Yes. Everything happens client-side in your browser — your JSON is not uploaded, stored, or analyzed. You can run API keys, token payloads, and internal configs through here without worry.
JSON Schema is a description language for JSON documents: it defines which keys are allowed, which types apply, and which fields are required. That lets you check API contracts automatically — instead of customer and API discovering only in production that the “amount” field should be a number and not a string.
The official specification: RFC 8259 (The JavaScript Object Notation Data Interchange Format). For everyday admin work with JSON on the command line, including jq tricks, check out our blog post JSON im Admin-Alltag. And if your JSON arrives as a Base64-encoded string: Base64 Decoder.
