Split Excel — No Uploads Required
Manage oversized workbooks more with our Split Excel tool. Large spreadsheets can be difficult to share, slow to open, and hard to manage. Our tool allows you to break down a single workbook into smaller, more manageable files. You can split by individual sheets, or divide a large sheet into multiple files based on a specific number of rows. This is essential for distributing data to different departments or preparing datasets for processing. All splitting happens locally in your browser for maximum security.
