Sometimes splitting a spreadsheet isn't about row count at all — it's about grouping. A sales report might need one file per region, an HR list one file per department, or an orders sheet one file per customer. Doing this manually with filters and copy-paste is slow and easy to get wrong once a column has dozens of unique values.
Turbo Large Data Splitter can split an Excel file based on the values found in a chosen column, automatically creating one output file for each unique value and placing every matching row into the right file. There's no need to sort, filter, or copy anything by hand.
- Install Turbo Large Data Splitter and open your Excel file in the app.
- Select "Split by column value" as the split method.
- Choose the column whose values should define the groups.
- Preview the detected unique values before running the split.

What happens if a cell in the split column is blank?
Rows with a blank value in the chosen column are grouped into their own file, so no data is left out of the split.
Can I split by a column that contains dates?
Yes, date columns work the same as text or number columns, with one output file created per distinct date value found.
How are the output files named?
Each output file is named after the unique value it represents, making it easy to identify which file belongs to which group without opening it first.
