CSV Uploader Built for SaaS

Powerful features to help you integrate a perfect CSV upload experience in your app.

CSV Column Mapping

Allow your users to match the file column headers to the predefined data model. CSVbox uses intelligent algorithms to automatically match columns so that the users don't have to. This is the end of import templates and messy column wrangling.

Client Side Validation

Before submitting the file, the users can fix validation issues right inside the upload widget. This ensures that the uploaded data is clean and ready to use.

Data Destinations

Convert cleaned CSV, XLS, TSV files to JSON or XML format and push the data to any API, Database or App or your choice.

Event Hooks

Setup webhook listeners to receive alerts about widget events such as import complete. Receive metadata including custom user attributes to identify the users in your app.

Import Links

Use Import Links to import spreadsheets without a website or app. Create a full import page in just a few clicks and share the link with your customers—no code required.

Dynamic Data Model

Do you require a unique sheet template for each user? CSVbox provides the flexibility to add unique dynamic columns for each import at run-time.


Validation Library

The importer comes with a large pool of pre-built validation rules. Set up your data model in minutes without writing any scripts.
