Does minifying change my data?

No. Only whitespace between tokens is removed; keys, values and their order stay exactly the same.

How do I unminify JSON?

Open the JSON Formatter (Beautify) tool, or press the format button above the Input box.

Is there a size limit?

No fixed limit. Large inputs run in a background worker, so the only limit is your device's memory.
