Preguntas frecuentes
Is my JSON uploaded to a server?⌄
No. Formatting, validation and minification run entirely in your browser with JavaScript. Your data never leaves your device, which makes this tool safe for API keys, customer data and other sensitive payloads.
How do I find syntax errors in JSON?⌄
Click Validate (or Format). If the JSON is invalid, we show the parser message plus the exact line and column of the first error, so you can jump straight to the problem — trailing commas, single quotes and unquoted keys are the most common causes.
What does “Sort keys” do?⌄
It recursively sorts every object’s keys alphabetically before output. Sorted JSON is easier to diff in code review and produces stable output for caching and hashing.
