About this tool
About this tool
CSV Column Splitter divides one column into multiple new columns by splitting on a delimiter or pattern inside your browser. You define target column names and the splitter handles quoted fields correctly during the operation.
Split one CSV column into multiple fields using a chosen separator. Use the full-width workspace to split content into useful parts while reviewing rows, columns, headers, delimiters, and values. The tool accepts CSV, provides focused options, and creates CSV output that you can inspect, copy, download, or save as a local draft.
Built for daily work
- Use CSV Column Splitter for data imports, spreadsheet cleanup, reporting, and database preparation.
- Divide large content, columns, rows, or values using the selected rule before content is imported, published, committed, shared, or passed to another application.
- Check a small sample interactively before applying the same operation to a larger tabular data workflow.
- Prepare cleaner CSV output for teammates, clients, documentation, testing, or downstream automation.

Copy or download the CSV result, save a browser-local draft, or open a related tool for the next conversion, validation, or cleanup step.
Key features
Key features
Split one column into multiple fields
Choose a column and a separator character, and the tool divides each value at every separator occurrence to create new columns from the resulting parts.
Configurable split separator
Use commas, spaces, pipes, hyphens, or any single character as the split point, making it possible to break apart values like "Smith, John, Jr" into separate fields.
Control the number of new columns
Set a maximum number of splits to prevent over-splitting values that contain the separator in unexpected positions, or split into as many columns as the data requires.
Original column preserved or replaced
Choose whether the source column stays in the output alongside the new split columns or is removed, depending on whether you still need the original combined value.

Limitations and important notes
Limitations and important notes
- Check the split rule and generated boundaries before downloading multiple results.
- Large or deeply structured input depends on available browser memory and may process more slowly on mobile devices.
- The tool implements practical browser-based processing and may not reproduce every feature of specialist desktop software or every vendor-specific extension.
- Keep the original source and review generated output before production, security-sensitive, financial, legal, or safety-critical use.
