Text Separator Tool — Convert Between Comma, Newline & Custom Delimiters

3 September, 2026 • 0 views • 1 minutes read

Free online text separator tool to split or join text by commas, newlines, tabs, pipes, or custom delimiters. Perfect for CSV, lists, and data cleaning.

Ever pasted a comma-separated list into a spreadsheet only to have it all land in one cell? Or needed to turn a column of data into a single line for an API call? The Text Separator tool solves this in one click — no scripts, no spreadsheet formulas, just paste and convert.

What the Text Separator Does

This tool converts text between different delimiter formats. You paste your input, choose the current separator (comma, newline, tab, pipe, semicolon, space, or a custom character), pick the output separator, and get the converted result instantly.

  • Comma ⇄ Newline — the most common use case: turn a CSV row into a vertical list or vice versa
  • Tab ⇄ Comma — handy for spreadsheet copy-paste workflows
  • Pipe ⇄ Newline — useful for Markdown tables or CLI output
  • Custom delimiters — handle odd formats like ;, |, ::, or multi-character separators

Real-World Use Cases

1. Cleaning up API responses

Many APIs return arrays as comma-separated strings. Paste the response, switch from comma to newline, and you have a readable list you can scan or feed into another tool.

2. Preparing data for SQL IN clauses

Got a column of IDs from a spreadsheet? Copy the column, paste into the tool with newline as input and comma as output. Wrap each value in quotes if needed, and you have a ready-to-use IN ('id1','id2','id3') clause.

3. Converting Markdown tables to CSV

Copy a Markdown table column (pipe-separated), set input to | and output to comma — instant CSV row.

4. Normalising messy logs

Log lines often use inconsistent spacing. Use the custom delimiter option to split on multiple spaces or specific patterns, then re-join with a clean single delimiter.

Why Not Just Use Find/Replace?

You can do this in any editor, but the Text Separator tool:

  • Handles trailing delimiters cleanly (no empty final element)
  • Preserves empty fields when they matter
  • Works on mobile without a keyboard shortcut hunt
  • Shows a live preview so you verify before copying
