"We love how easy CSVbox made it to integrate file uploads into our product. We started with a self-built version and it was buggy and hard for people to use. CSVbox solved this for us and only took an hour to integrate."
Ship CSV imports in an afternoon.
Not next quarter.
Drop in one widget. Users upload CSV, Excel, and PDFs — they map columns and fix bad rows in-browser. You receive clean, typed data at your webhook. SOC 2 + GDPR included on every plan.
Why CSVBox
"It's just an upload form" — until it isn't
The CSV parser is 5% of the work. Mapping UX, locale dates, Excel quirks, 500 MB files, server-side validation — that's the other 95%, and it becomes a permanent maintenance tax. CSVbox replaces all of it.

The product
An embeddable importer your users will love
CSVBox drops a complete import experience into your app — file upload, column mapping, validation, and delivery — as a single embeddable widget.
Embed anywhere
One JS snippet adds a polished import modal to any web app.
Smart mapping
AI auto-matches columns. Users confirm with a click.
Inline validation
Errors surface per-row before data ever leaves the widget.
Clean data out
Validated rows pushed to your webhook, API, or database.
How it works
Embed a CSV importer in 3 steps
Production-ready imports in three steps — no SDK, no server-side scaffolding.
Configure your schema
Define schema, setup validation rules, transform functions and destination settings.
Embed the widget
Add the JS snippet to your app. Or share the Import Link.
Receive clean data
Users upload sheets. You get clean data in your app, API or DB.
Features
Every edge case you’d otherwise build yourself
Nine years of production imports, rolled into one drop-in widget. Ship the feature — don’t maintain it.
Uploads that work on phones
A polished modal your users actually finish. CSV, TSV, and Excel up to 500 MB, streamed — no frozen tabs.
Column mapping users don’t fight
AI-powered fuzzy matching proposes the right header; users confirm or override with a dropdown. No more "where do I put Email2?" support tickets.
Catch bad rows before your DB does
Built-in rules plus custom JavaScript and server-side checks — errors surface at the cell, row, or table level, before they ever reach your API.
Transform on the way in
Server-side JavaScript transforms — date normalization, unit conversion, lookups — clean the data before it lands in your system.
Delivered where you need it
Push validated rows straight to your webhook, Postgres, MySQL, Airtable, Google Sheets, Zapier, n8n — 20+ destinations, no ETL.
Scales to 500K rows
Streamed uploads, chunked validation, progressive UI — giant catalogs and multi-hundred-MB files don’t freeze the browser.
On-brand and white-label
Full theming via CSS variables and your logo, colors, language. Mobile-ready flow with progress tracking and inline error correction.
AI where it earns its keep
Column mapping + transforms powered by AI where it helps — and users can always override. No black-box magic, no hallucinated fields.
