Kort sagt: JSON er webbets dataudvekslingsformat. En formatter gør uoverskuelige payloads læsbare, finder syntaksfejl og forbereder data til API’er, configs og logs.
1) Hvad er JSON
JSON (JavaScript Object Notation) er et tekstformat til lagring og overførsel af strukturerede data. API’er, configs, logs og webhooks bruger det hver dag.
2) Hvorfor du har brug for en JSON-formatter
- Readability. API responses often arrive as one long line.
- Error finding. A trailing comma or missing brace breaks parsing.
- Debugging. Easier to inspect fields before sending a request.
- Sharing. Pretty JSON is easier to paste into docs and chats.
- Minifying. Sometimes you need a compact payload.
3) Formater, minify og valider
- Format — add indentation for humans.
- Minify — compress into one line.
- Validate — check syntax without rewriting.
En formatter retter ikke datas betydning — kun syntaksen.
4) Almindelige fejl
- Trailing commas:
{"a":1,} - Single quotes:
{'a':1} - Unquoted keys:
{a:1} - Comments inside JSON
- Mixing JSON with JS objects or YAML

6) FAQ
Is it safe to paste sensitive data?
Processing happens in your browser. Still avoid pasting passwords unless necessary.
How is this different from editor beautify?
Same idea — useful when you need a quick check without opening an IDE.
Can I edit JSON in the field?
Yes. After edits, click Validate or Format again.
