Delimited Column Extractor

Pick a delimiter (comma, semicolon, tab, pipe, anything) and extract a single column from every line. Useful when a CSV is too messy for a spreadsheet but you only need one field.

How it works

Each line is split by the delimiter you chose. The 1-based column index selects which piece to keep. Missing columns become empty strings, never errors. Optional trim removes surrounding whitespace from each cell.

How to use it

  1. Paste the delimited text

    Drop in a CSV, TSV, log file, or any line-based text where each row has consistent fields.

  2. Pick delimiter and column

    Comma, semicolon, tab, pipe, or a custom string. Then enter a 1-based column index to extract from every line.

  3. Toggle trim and extract

    Trim removes surrounding whitespace from each cell. Missing columns become empty strings, never errors. Run the extraction.

  4. Copy the column

    Take the single-column output into a SQL IN clause, a redirect map, or the input of another tool in the pipeline.
