Quick deploy in hours

“I can’t wait to build another data importer,” said no one, ever. Flatfile revamps entire CSV import flows for SaaS products in a fraction of time.

I’ve built a data importer before. After weeks of development time we still ran into bugs, and our users had to slog through a massive FAQ. It was a full time job! Compare that to Flatfile, which took us less than a day to implement.

How it works

Flatfile is a javascript snippet that integrates easily with any web application, framework, or API.

Get a license key

Once you have registered for Flatfile, you’ll get a license key that connects your application to Flatfile.

Configure the importer

After obtaining your license key, you can configure your Flatfile JS snippet with your expected data model and validation options.

Deploy Flatfile

Once the importer is configured, you simply need to tell it where and how to send the import results. After that, all you need to do is add Flatfile as a button in your application.
