Form Data Injector

Inject test data into web forms via JSON. For developers and QA engineers.

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
