Online CSV splitter for large and sensitive data

Many online CSV tools want full access to your data with little transparency about where it goes. If your files contain customer records, internal logs, or financial information, you need more control than that.

DataForge is designed as a privacy-first CSV splitter. Your file is transferred securely to the server for processing over HTTPS, split into smaller outputs based on your settings, and made available for download as soon as the job finishes. You stay in control of the workflow: you decide how many rows you want per file, when to start conversion, and when to delete the temporary results. Combined with our no-ads, no tracking approach, this makes DataForge a good fit for teams who care about data protection but still want the convenience of a focused online tool.

FAQ

Is DataForge safe for sensitive CSV data?

Yes. Your CSV is transferred over HTTPS and processed only to run the conversion you requested. We do not use your data for advertising or share it with third parties, and you can remove temporary outputs with the delete button once you have downloaded them.

How long are my files kept on the server?

Files are stored temporarily so you can complete the conversion and download the results. After that, you can delete them immediately from the tool. Our backend also cleans up old sessions automatically within 24 hours.

Do I need to install anything to use the CSV splitter?

No. DataForge runs in the browser and communicates with the API over HTTPS. You just open the site, upload your CSV, configure how to split it, and download the resulting files without installing desktop software or writing scripts.
