How to Split Excel Sheets into Separate Files

Large Excel files can be a nightmare to manage. Whether you have a 50-sheet workbook or a million-row data dump, learning how to split them is accurate essential skill.

Method 1: Splitting by Sheet

This is common when you have monthly reports (e.g., "Jan", "Feb", "Mar") in one file and need to email them to different departments.

1. Open iloveexcel.co and select the Split Tool.
2. Upload your multi-sheet workbook.
3. Select "Split by Sheets" mode.
4. Click Split. You'll get a ZIP file containing each sheet as a standalone .xlsx file.

Method 2: Splitting by Rows

Excel has a row limit (approx 1 million). If you're dealing with massive CSV exports, you often need to chunk them into smaller files (e.g., 1000 rows each) for easier processing.

1. Upload your large data file to the Split Tool.
2. Select "Split by Rows".
3. Enter the number of rows per file (e.g., 500).
4. The tool will automatically calculate how many files are needed and generate them instantly.
