Frequently Asked Questions
What does the Row Splitter tool do?
It takes rows where a cell contains multiple values separated by a delimiter (like commas) and splits them into separate rows. Each split value gets its own row with the same data from the other columns.
What delimiters are supported?
The tool supports comma (,), semicolon (;), pipe (|), newline, and custom delimiters. You can choose the one that matches your data.
Will my other columns be affected?
No. Only the selected column is split. All other column values are duplicated exactly as-is into each new row.
Can I use this with CSV files?
Yes! The tool supports both Excel files (.xlsx, .xls, .xlsm, .xlsb) and CSV files (.csv, .tsv). The output is always downloaded as an Excel file.
Is my data safe?
Absolutely. All processing happens locally in your browser. Your files never leave your device or get uploaded to any server.
