JSON-formaterare

Paste JSON to pretty-print or minify it. The parser runs in your browser so the document does not need to leave the device for this task.

Snabbsvar

It parses the text as JSON and reprints it with indentation, or compactly, or reports the first syntax error.

Exempel: {"a":1} becomes a two-line pretty document with an indented key.

Beräkningarna följer formeln på den här sidan; avrundning och enheter kan ändra sista siffran. Behandla resultatet som en pedagogisk uppskattning.

Vad kalkylatorn gör

It parses the text as JSON and reprints it with indentation, or compactly, or reports the first syntax error.

Vem den är till för

Developers checking API payloads, config files or a copied object.

Så fungerar beräkningen

JSON.parse on the input, then JSON.stringify with a chosen indent. Errors come from the parser, not from a server.

Formel

Parse → reprint. No numerical formula.

Antaganden

Vanliga frågor

Why did it fail on a trailing comma?
Standard JSON does not allow trailing commas. Remove them or convert the file.
Is my data sent to Toollabz?
Formatting runs in the browser. Do not paste secrets into any third-party page if your policy forbids it.
