300+ Customers

Trusted by teams across the world

Looking to build a CSV upload feature in your app?

It sucks up valuable engineering time and can still fall short of expectations.

Handle Technical Edge Cases

What if there are commas or quotes inside the fields? What if I put a BOM in the file? What if there is invalid or missing escaping? Cryptic error messages can wear you down.

Address User Experience

Users hate having to read documentation or watch video tutorials on how to format and upload spreadsheets. A bad upload experience can cause the users to question the value of the main product itself.

Code Advanced Import Features

Trying to bake in advanced functionality such as CSV column matching, data validation, error handling, user experience, and security is like building an entirely new product in itself.

Strain on Resources

The support team has to deal with additional tickets from frustrated customers who are struggling with imports. Many times it can lead to your team manually cleaning the data and uploading it to the backend.

What if...

  • You could add the data import functionality to your web app in only a few minutes?
  • Your users have a flawless upload experience each time?
  • You'd save thousands of dollars in building and maintaining a CSV data importer?

CSV Uploader that Your Users will Love

Give your users a sophisticated upload experience. Cut inefficiencies and reduce the risk of churn with flawless onboarding.

Pick a file

With a simple file picker, the users select a spreadsheet that needs to be uploaded.

Map columns

Users map the CSV column headers to the predefined data model. The widget also provides automatic column matching recommendations. This is the end of messy spreadsheet preparation!

Validate data

Before submitting the file, the users can fix validation issues right inside the widget. This ensures that the uploaded data is clean and without formatting errors.


Users submit the spreadsheet and monitor the upload. You receive ready-to-use data in your app, database or API.

Get Started in Minutes

Implement a production-ready data importer in minutes, not weeks. Speed data onboarding and customer time-to-value at the same time saving hundreds of dollars.

Create a template

Define your data model and configure the validation rules with just a few clicks.

Configure data destination

Specify where you want to receive the data and in what format. It could be an API, database, or a third-party app.

Embed code

Add the JS snippet in your app and start accepting files. Alternatively, share the sheet Import Link with your users to collect files even without an app.

Affordable Pricing

From solopreneurs to established startups - businesses power imports with csvbox.
