Split large CSV files into multiple Excel files online

Huge CSV exports quickly become unmanageable in Excel. Files open slowly, freeze your workbook, or fail to load all rows, so even simple checks and filters turn into a frustrating waiting game.

With DataForge, you upload your large CSV once and let the server do the heavy lifting. Choose how many rows you want per file, start the conversion, and watch the progress bar as we split your data into a series of smaller, Excel-friendly outputs. When the job is done, you can download a clean, numbered set of files that open quickly in Excel, BI tools, or databases. Files are transferred securely to the server for processing and kept only as long as needed for conversion and download. When you are finished, use the "Delete files" action in the tool to remove your temporary outputs from the server.
