Veelgestelde Vragen

What is JSON formaatting?

JSON formaatting (or pretty-printing) adds proper indentation and line breaks to JSON data, making it human-readable. Compact JSON is great for transmission but hard to read.

Does the hulpmiddel handle nested JSON?

Yes, the formaatter handles any depth of nested objects and arrays, correctly indenting each level. Complex deeply-nested JSON structures are formaatted beautifully.

Worden mijn gegevens naar een server verzonden?

No. All JSON processing happens entirely in uw browser. uw data never leaves uw device.
