About Form Data Injector
Form Data Injector is a lightweight Chrome extension for front-end engineers and QA testers who need to fill web forms repeatedly with consistent test data — without typing the same values over and over.
## ✨ Features
- One-click injection — fill every field on a form instantly from a saved preset
- JSON mode — define field-value pairs as plain JSON for full control
- Table mode — edit fields in a spreadsheet-style table; no JSON knowledge required
- Scan page — detect all input, textarea, and select elements on the current page and pre-populate the table with their selectors and current values
- Named presets — save multiple field sets with custom names and load them any time
- CSS selector support — target fields by name attribute, #id, or any valid CSS selector
- React / Vue compatible — fires native input, change, and blur events so controlled components update correctly
- Supports input, textarea, select, checkbox, and radio elements
- Lightweight and fully offline — no external requests, no telemetry
## 🔒 Privacy
This extension does not collect, store, or transmit any personal data.
All functionality runs locally in the browser. Presets are stored in your browser's local storage only.
## ⚡ Use Cases
- QA regression testing — reproduce exact form states in seconds
- Development — fill long sign-up or checkout forms during UI work
- Admin panels — quickly switch between different user data sets
- Form auditing — scan a page to discover all form fields and their current values
