Frequently Asked Questions
Testimonials
We'd looked at other tools but ExpressCSV felt like the modern and code-first option. Up and running in ~20 minutes and replaced our custom importer, we've never looked back.
Nick Taylor
CTO, Weldmet
We deal with sensitive customer data, so the fact that imports run entirely in the browser and never hit ExpressCSV's servers was a huge deal for us. Security review was basically a non-event.
