Form to JSON – Form Data Extractor

Extract web form data to JSON. Preview and select fields, copy or download JSON, and save optional local snapshots.

Extract filled web form data into JSON without submitting the form. Form to JSON helps developers, QA testers, and anyone transferring form information between tools. Read supported form fields from the current webpage, review their values, choose what to include, and copy or download structured JSON. KEY FEATURES • Extract native form controls, including text inputs, textareas, dropdowns, radio buttons, checkboxes, and date/time fields. • Choose one form or extract multiple forms separately. • Preserve repeated fields, empty values, leading zeros, and original date/time values. • Capture multiple selected dropdown options and checkbox states. • Review extracted values and exclude fields before exporting. • Search the field preview by label or value. • Choose readable labels or original field names for JSON output. • Copy JSON to your clipboard or download a .json file. • Save optional local snapshots, reopen them, and delete them when no longer needed. • Restore your preview and selections when reopening the popup during the browser session. HOW TO USE 1. Open a webpage containing a form. 2. Click the extension and choose “Read this page.” 3. Review the extracted fields and uncheck anything you want to exclude. 4. Copy your JSON or download a file. LOCAL PROCESSING Form data is processed on your device. The extension does not send extracted data to a server or use analytics or AI services. Password and hidden inputs are excluded. Other fields may contain sensitive information, so review your selection before sharing or saving. Previews are remembered temporarily in browser session storage. Permanent snapshots are saved locally only when you choose “Save a copy.” COMPATIBILITY Designed for supported native HTML form controls. Accessible same-origin frames and open shadow roots are supported. Custom widgets, closed shadow roots, and inaccessible frames may not be captured. Form to JSON reads current values without changing or submitting forms.
