If you need a form builder that integrates with Google Sheets and lets you upload files, Sheet Monkey is a great option. This platform-agnostic tool makes it easy to set up form submissions without any backend programming. It supports Google Sheets, but also Webflow, WordPress and Squarespace. Sheet Monkey also offers email notifications, automatic redirects and a drag-and-drop form builder, so it's good for landing pages and email capture. It also offers pricing tiers, including a free option, so it's good for a variety of needs.
Another contender is Softr, a no-code tool that lets you create custom client portals, internal tools and community forums. Although it primarily pulls data from Airtable and Google Sheets, it can handle file uploads. Softr's drag-and-drop interface and detailed permission controls make it easy to use, and its integration with tools like Zapier and Mailchimp expands its utility. The company offers several pricing tiers, including a free plan, so it's good for small businesses, startups and enterprises.
