About this Tool
Use this Column Splitter when one field contains several values that should become separate columns. The tool splits by delimiter, split at a fixed position, limit the number of splits, trim results, and name the new columns before export. It is focused on splitting one existing column, unlike Text to Columns, which starts from pasted structured text.

Frequently Asked Questions
What if a row has fewer split parts?
Missing parts become empty cells so each row still has the same columns.
Can I keep the original column?
Yes. You can keep, hide, or remove the original combined column.
Can the split delimiter be customized?
Yes. Common delimiters such as comma, space, slash, pipe, and custom text are supported.
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.
