About this Tool
Use this Table Splitter to break one dataset into smaller outputs. The modes split by a column value, by fixed row count, or by selected columns. It is useful when a single export needs to become separate department files, smaller chunks, or focused column sets while keeping the operation visible and reversible before download.

Frequently Asked Questions
Is my table data uploaded to a server?
No. The tool parses, transforms, previews, and exports data locally in your browser without uploading your input.
Can I split by unique values in a column?
Yes. Split-by-column mode creates one result per selected value, with clear names for each output.
Can headers be repeated in each output?
Yes. Exported CSV and table outputs should include headers by default unless the user turns them off.
Are row batches exact?
Fixed-size batches should contain the selected number of data rows, except the final batch, which may contain fewer rows.
What file sizes are practical in the browser?
Small and medium tables are the best fit. Very large files can use a lot of memory because parsing, previews, and exported results all live inside the browser tab.
