What is List Converter?

A list converter transforms items separated by one delimiter into another format, useful for data migration and format normalization.

How It Works

Splits the input by the source separator, trims whitespace, filters empty items, then joins with the target separator or formats as JSON/CSV.

Common Use Cases

  • Converting newline lists to CSV
  • Creating JSON arrays from comma lists
  • Normalizing data formats

Technical Details

Input separators: newline, comma, space, semicolon, tab, pipe. Output: same + JSON array + CSV (with quoting).

How to Use

  1. Paste your list
  2. Select source and target separators
  3. Click Convert
