Split your Excel sheets based on column values, row count, or custom ranges

This Excel Data Splitter automates the manual process of dividing large spreadsheets into manageable sections. Instead of copying and pasting data between sheets or files, you can quickly separate datasets based on specific criteria, saving hours of manual work. If you need to combine files before splitting or after processing, consider using the Excel file merger to consolidate your data first.
Split by Column Values: Groups rows based on unique values in a selected column. For example, splitting customer data by "Country" column creates separate files for each country. After splitting, you can convert these files to CSV for use in other applications.
Split by Row Count: Divides data into equal chunks. Ideal for splitting files that exceed email attachment limits or system import restrictions.
Split by Range: Creates sequential sections starting from a specific row. Useful for extracting specific data segments from large reports.
Custom Split Criteria: Uses conditional logic (equals, contains, greater than, etc.) to separate data based on specific criteria. For advanced data preparation, pair this with the data cleaner tool to standardize values before splitting.
Formatting Note: When "Keep Original Formatting" is enabled, basic cell formatting (fonts, colors, borders) is preserved. Complex formatting like conditional formatting rules or data validation may not transfer perfectly across all spreadsheet applications. You can rebuild these rules later using the conditional formatting tool if needed.
Important: Always verify your source data before splitting:
No, this tool requires unprotected Excel files. Please remove password protection before uploading.
You can split one sheet at a time. After splitting the first sheet, you can reload the file and select a different sheet.
Performance depends on your browser and device memory. For optimal results, files under 50MB work best. For larger datasets, consider splitting by row count first.
This is a browser-based tool requiring internet connection for initial load. All processing happens locally in your browser for privacy.
Your Excel files never leave your computer. All processing occurs entirely within your browser using JavaScript. No data is transmitted to our servers or stored anywhere.
This tool complements other Excel utilities available on Toolsrail. For instance, after splitting your data by department, you might need to convert specific sheets to Google Sheets format for online collaboration. If you're working with large datasets that require validation, consider running the split files through the data validation tool to ensure accuracy. For those dealing with time-based splits, the date calculator can help you define precise ranges before using the "Split by Range" method.
