Sometimes a CSV is too big for downstream tools, or you want to break a single export into one file per region/customer/category. This tool does both. Choose 'Every N rows' for a size-based split, or 'By column value' to get one CSV per distinct value in a column. Every chunk keeps the original headers so each output is self-contained.
Drag from Finder, click to choose, or paste data directly into the input pane.
Tool controls appear above the output. Tune them and watch the result update live.
Download the cleaned-up file, or click 'Build dashboard' to see what's actually in your data.
Every other CSV utility online makes you upload your file and wait. Ours runs in your browser, instantly, and surfaces what's interesting in the data while it's at it.
Parsed locally — open DevTools → Network and you'll see zero requests when you drop a file.
Tool runs as you change parameters. No 'Convert' button to wait on.
Below the output, a strip tells you what's actually in the data — concentrations, outliers, suggested chart.
If the data made you curious, hit 'Build full dashboard' and it opens in our visualization tool.
