Turn any HTML form into a working backend in minutes. Point your form's action at one URL and every submission lands in your Google Sheets™ spreadsheet instantly — no server, no API keys, no code beyond one line. Prefer AJAX or a JSON API? Submit with fetch() and get a JSON response back — works great for single-page apps and JS frameworks too.
Whether you're coding a form by hand or want one built for you, CodeAddon Forms connects it straight to your spreadsheet — or use our no-code Generator if you'd rather not write any HTML at all.
