Browser Batch Worker — CSV Form Filler

Fill repetitive web forms from CSV with reusable mappings, retries, resume checkpoints, and local-only processing.

Browser Batch Worker turns repetitive web form entry into a reusable CSV workflow. Load a CSV file, scan the current web page, review the automatically detected field mapping, test one row, and then process additional rows as a controlled batch. Key features • Automatically maps CSV columns to web form fields • Manual field mapping when automatic matching needs adjustment • Supports text fields, text areas, select menus, datalists, radio buttons, checkboxes, dates, numbers, ranges, and color inputs • Handles many dynamically rendered forms with resilient field re-matching • Supports open Shadow DOM and same-origin iframe form controls • Supports multi-step workflows using Next / Continue / Submit / Save actions • Verifies submissions and can retry failed rows • Exports failed rows and complete batch results • Saves reusable mappings for repeated workflows • Generates CSV templates from scanned forms • Mapping profiles can be exported and imported • Interrupted batches can be resumed from a locally saved checkpoint Privacy-first local processing CSV data is processed locally in your browser. Browser Batch Worker does not upload your CSV data to its own server and does not include advertising or analytics SDKs. Website access is requested only for a site that you explicitly select for automation. Safety Browser Batch Worker intentionally skips common sensitive fields such as passwords, file uploads, one-time codes, payment card fields, CVV/CVC fields, Social Security Number fields, and bank account or routing-number fields. Before running a batch, you can review the target site, row count, mappings, action, and verification settings. Testing a single row first is recommended for a new website. Browser Batch Worker is intended for legitimate repetitive data-entry workflows on websites you are authorized to use.
