Frequently Asked Questions
Answers to popular questions about client-side Excel splitting.
Q.How does column splitting work?
The splitting engine reads your spreadsheet and groups rows by the unique values in your chosen column. For example, if you choose a "Country" column, the tool creates a separate Excel workbook for USA, Canada, Germany, etc.
Q.Are my spreadsheets uploaded to any server?
No. All processing, parsing, grouping, and ZIP compression happens entirely client-side inside your browser using JavaScript. No files or cell values are ever uploaded to external servers.
Q.Is there any limit on the file size?
There are no strict limits from our software. Since it runs in-browser, it depends on your device memory. The tool comfortably handles files with hundreds of thousands of rows.
Q.What happens to empty values in the split column?
You can choose how to handle empty values: you can skip those rows entirely, or group them into a separate spreadsheet file (e.g. "Empty.xlsx" or "Other.xlsx").
