Excel Sheet Splitter
Split one .xlsx/.csv dataset into multiple Excel files based on a selected column value.
100% client-side: parsing, grouping, and file generation run only in your browser. No data is uploaded.
Import file
Click or drag a .xlsx or .csv file here
Load one file, choose a column, then export grouped outputs as ZIP
Split configuration
0 rows • 0 output files
Upload a file and choose a column to preview generated files.
Each generated file keeps the same columns and contains rows where the selected column has that value.
Column-Based Split
One dataset in, many files out. Each unique column value becomes a separate Excel file.
Batch ZIP Export
Download all generated files in one ZIP package ready to share or archive.
Local-Only Processing
Rows are parsed, grouped, and exported directly in-browser without server upload.
