Json Filler is a Chrome extension designed to boost developer productivity by automatically filling JSON inputs (like in Swagger UI) with realistic, context-aware dummy data.
It recursively parses your JSON schema and generates smart data based on keys (e.g., email, phone) and preserves the format of existing numbers.
You can download the Json Filler Chrome extension from the Chrome Web Store.
- Context-Aware: Detects keys like
email,phone,uuid, anddateto generate relevant data. - Smart Numbers: Preserves the length and decimal precision of example numbers.
- Deep Parsing: Works with deeply nested objects and complex arrays.
- Privacy Focused: All generation happens locally in the browser.
