List Converter & Text Processor

What is a List Converter & Text Processor?

The List Converter allows you to batch-process column text data: add prefixes/suffixes, join lists with custom delimiters (commas, quotes), sort, deduplicate, reverse, and transpose rows.

Why Use This Converter?

  • SQL Query Building: Convert a column of IDs into a comma-separated SQL IN clause (`IN ('id1', 'id2')`).
  • Programming & Code: Format raw text lists into JSON arrays or JavaScript array literals.
  • Data Cleanup: Trim whitespace, strip empty lines, and remove duplicate entries from list items.

How to Use

  1. Paste your list into the text area.
  2. Choose transformations (Add Prefix/Suffix, Wrap in quotes, Join with delimiter, Sort, Deduplicate).
  3. Copy the converted formatted list.

Real Conversion Example

Input (TEXT):

apple
banana
cherry

Output (TEXT):

"apple", "banana", "cherry"

Important Technical Details & Mechanics

  • Pipeline Processing: Chain multiple transformations (e.g., Deduplicate -> Sort -> Add Prefix -> Join).
  • Regex Line Splitting: Handles CRLF and LF line endings seamlessly.
  • Client-Side Speed: Processes thousands of rows in milliseconds.
