Split a single CSV column containing combined values into multiple separate columns. Choose any delimiter — comma, space, dash, or custom string.
Open CSV Column Splitter → free, no sign-inA common data quality problem: a single column contains values that should be in separate columns — 'First Last' in a name field, 'City, Country' in a location field, or anything combined with a consistent delimiter. The CSV Column Splitter solves this directly: select the column, specify the delimiter, and the tool creates the new columns. The output CSV has the original data restructured correctly.
Data analysts cleaning imported data, developers preparing CSV files for database import, anyone who receives CSV exports where multiple values have been combined into a single column that should be separated.

One job, done well. CSV Column Splitter was built to solve a specific problem cleanly. No feature bloat, no ads, no distractions.
What if values have different numbers of parts?
Empty values are used for missing parts — rows with fewer parts than the maximum get blank cells in the extra columns.
Can I split by a multi-character delimiter?
Yes — any string can be used as a delimiter.
Are the original data intact?
Yes — the original column remains; new columns are added alongside it (or replace it depending on your settings).
What column names are used for the new columns?
Auto-generated names based on the original column name (e.g. Name_1, Name_2).
Can I split multiple columns in one pass?
Process one column at a time and chain the operations by uploading the result back.
