What does this tool do?
Column Extractor pulls a single column out of delimited text in seconds. It's handy for anyone who needs just one field — say the email or name column — from a CSV, a log file, or table data pasted from a spreadsheet.
How to use it
- Paste your text into the input area.
- Adjust the options to fit your needs.
- Copy the processed text.
How to use it
Paste your data into the left box; each line is one record. Choose the delimiter: comma, tab, semicolon, space, or pipe (|). Enter the zero-based column number — 0 is the first column, 1 the second. The tool splits each line on the delimiter and extracts the column you picked. You can join the output by new line, comma, or space, then grab it with the Copy button.
Common scenarios
Great for lifting just the email column out of a CSV to build a mailing list, pulling ID numbers from a tab-separated export, or extracting IP addresses from log lines. Set the output separator to comma to flatten the values into a single inline list, or to new line to stack them for feeding into another tool such as a text sorter or deduplicator.
Frequently asked questions
Where does column numbering start?
At zero. Use 0 for the first column, 1 for the second, and so on. If a line has no value at that index, an empty result is returned for that line.
Which delimiters are supported?
Comma, tab, semicolon, space, and pipe (|). You can choose the input delimiter and the output separator independently.
Does it handle quoted CSV fields?
No, it does a simple split, so it won't parse quoted CSV fields that contain the delimiter inside them. It works best on plain, unquoted delimited data.
