How it Works
Upload Your Excel File
Select the Excel workbook (.xlsx, .xls, .csv) you want to split. Drag and drop it into the tool or click to browse your computer.
Choose Your Split Method
Pick how to split: by sheet (each sheet becomes its own file), by row count (split into chunks of N rows), by column value (split by a category column), or by delimiter (split text or names in a column).
Configure Options
For name splitting, choose your delimiter — space, comma, or custom. For file splitting, choose output format (.xlsx or .csv) and whether to include headers in every file.

Frequently Asked Questions
How do I split an Excel file into separate sheets?
Upload your workbook and choose 'Split by sheet'. Each sheet in your workbook becomes its own .xlsx file. Download all split files as a ZIP archive instantly.
How do I split first and last name in Excel?
Upload your Excel file, select the column containing full names, choose your delimiter (space or comma), and download the result with separate First Name and Last Name columns — no formulas needed.
How do I split a cell in Excel by delimiter?
Upload your file, select the column to split, choose your delimiter (comma, space, pipe, tab, or custom), and our tool splits every cell in that column into separate columns automatically.
How do I split text in Excel into multiple columns?
Use our Split Text tool — upload your file, choose the column with combined text, set your delimiter, and download the file with your text split into separate columns. Works exactly like Excel's Text to Columns but faster.
How do I split an Excel workbook by row count?
Upload your file and choose 'Split by rows'. Set the number of rows per output file (e.g. 1000), and our tool creates as many files as needed — each file includes the original headers.
How do I split Excel data by a column value?
Choose 'Split by column value', select the column (e.g. Region or Department), and our tool creates one separate .xlsx file for each unique value in that column.
Can I split a workbook with hundreds of sheets?
Yes. Our tool can handle workbooks with hundreds of sheets and extract them all at once into separate files. Download everything as a ZIP archive.
Will splitting change my original file?
No. Your original file is never modified. Our tool reads the file in your browser and creates new output files — your source file stays exactly as it was.
How do I split an Excel column by comma?
Upload your file, select the column to split, choose comma as your delimiter, and download the result. Works for addresses, tags, categories, and any comma-separated values in a cell.
Is it safe to split Excel files with personal data?
Yes — completely safe. Your files are never uploaded to any server. All processing happens locally inside your browser. Your data stays on your computer at all times.

No. MergeExcelFiles.org works entirely in your browser — Chrome, Edge, Safari, Firefox. No Microsoft Office, no software installation, and no account required.
How do I split last name and first name in Excel?
Upload your file, select the full name column, choose comma as the delimiter (for 'Smith, John' format) or space (for 'John Smith' format), and download the result with separate columns for last name and first name.
