In breve: JSON è il formato di scambio dati del web. Un formattatore rende leggibili payload confusi, individua errori di sintassi e prepara i dati per API, config e log.
1) Cos’è JSON
JSON (JavaScript Object Notation) è un formato testuale per memorizzare e trasferire dati strutturati. API, config, log e webhook lo usano ogni giorno.
2) Perché serve un formattatore JSON
- 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) Formattare, minificare e validare
- Format — add indentation for humans.
- Minify — compress into one line.
- Validate — check syntax without rewriting.
Un formattatore non corregge il significato dei dati — solo la sintassi.
4) Errori comuni
- Trailing commas:
{"a":1,} - Single quotes:
{'a':1} - Unquoted keys:
{a:1} - Comments inside JSON
- Mixing JSON with JS objects or YAML
