Combine Three Columns
Paste three one-field-per-row columns, optionally parse quoted CSV or TSV fields, and copy the combined text locally.
A QUICK WALKTHROUGH
How to use this tool
- Paste one value per row in all three columns.
- Choose line, CSV, or TSV input and the output delimiter.
- Combine matching rows, review the result, and copy it.
Position-based rows
Three inputs must contain the same number of rows, including empty rows. Values are combined in first, second, third order and no row is silently dropped.
Quoted CSV and TSV fields
Line mode treats each physical line as a value. CSV and TSV modes accept one field per row, including commas or tabs inside double-quoted fields, doubled quotes, and quoted line breaks. Extra fields or unclosed quotes are rejected.
Local and bounded workflow
Parsing and combining happen in the browser; nothing is uploaded. Use a delimiter such as a space, comma, or tab for the output.
GOOD TO KNOW
Common questions
Can values contain commas or tabs?
Yes. Choose CSV or TSV and wrap a value containing the input separator in double quotes; doubled double quotes are accepted.
What if row counts differ?
The tool reports an error and leaves the result empty until all three inputs have the same row count.
Are empty rows preserved?
Yes. Empty rows count as rows and are combined with the selected output delimiter.
