FAQ
What does minification do?
Strips all whitespace, tabs, and newlines from your JSON. Reduces byte size for network payloads.
What makes JSON invalid?
Common issues: single quotes instead of double, trailing commas, unquoted keys, mismatched brackets.
Can it handle large files?
Yes. Everything runs in your browser. Files up to several megabytes parse comfortably without server delays.
What does stringifying/unstringifying do?
Stringify escapes nested double quotes for safe storage in databases or nested JSON. Unstringify parses escaped string containers back to structured JSON recursively.
How do the Global, Key, and Value search filters work?
Global Search checks the entire document. Key Search matches only property keys. Value Search checks string values, numbers, and booleans — excluding object keys.
