Validation
Catch problems before they hit your database
Flag duplicate rows, missing values, and formatting issues early so teams can fix problems in context instead of debugging imports later.
Here's how ExpressCSV helps you stay ahead of bad data:
- Validate rows before anything is imported
- Highlight duplicate, missing, or malformed values
- Add custom sync and async validation rules

Your data stays in the browser
Work happens in the browser. Your onData callback gets typed rows to send to your backend, which means sensitive data never hits our servers.

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.

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.
