}Frequently asked questions
Does JSON Beautifier work offline?
Yes. Formatting, minifying, validation, tree view, and the local library work on your Android device. Android may also show cloud locations in its file picker. Choose a file already available on your device when you are offline.
What is the difference between formatting and minifying?
Formatting adds whitespace and indentation for readability. Minifying removes whitespace between JSON tokens for a more compact result. Both preserve the values and the whitespace inside quoted strings.
How do I fix an invalid JSON file?
Home shows an explanation with a line and column. Tap the message to move the cursor. Check that object keys and strings use double quotes, and remove trailing commas before closing braces or brackets.
