Delimited Text Extractor — Pull One Column from CSV or TSV
Extract one column from CSV, TSV, or any delimited text. Pick by column number or header name. RFC 4180 compliant.
How to use
- 1 Paste your CSV / TSV / pipe-separated text.
- 2 Pick the delimiter and indicate whether the first row is a header.
- 3 Choose by column number (1-indexed) or by header name.
- 4 Copy the one-value-per-line output.
Why use this tool
- RFC 4180 CSV parser handles quoted fields, escaped quotes, embedded newlines.
- Pick by header name — column position changes do not break your workflow.
- Custom delimiter for unusual separators (regex-free, plain string match).
- Output one value per line — ready to paste into another tool or spreadsheet column.
Frequently asked questions
Are columns 0-indexed or 1-indexed?
1-indexed — column 1 is the leftmost. This matches how non-programmers think about spreadsheets.
What if a row is missing the picked column?
You get a blank line in the output for that row, so positional alignment with the input is preserved.
Does header-name match care about case?
Yes — case- and whitespace-sensitive after a single trim on each side. Pick "by number" if your headers are inconsistent.

What is Delimited Text Extractor?
A Delimited Text Extractor is a tool that pulls a single column out of CSV, TSV, or any delimited text. It can select the column by its number or by its header name and parses input in an RFC 4180 compliant way. Running entirely in the browser, it extracts column data without uploading files to a server, handling quoted fields and varied delimiters correctly.
Features
Pick by number or header
Extract a column by its 1-based index, or by matching a header name in the first row.
