Replace Spaces With Comma

The Replace Spaces With Comma tool is a fast, privacy-friendly online utility that converts spaces — or any whitespace — in your text into a comma, semicolon, pipe, or any custom separator you choose. All processing runs entirely in your browser, so your data is never sent to any server.

⭐ What Does This Tool Do?

It scans your input text and replaces every space (and optionally tabs and line breaks) with the separator you specify. You can use one of the quick-preset buttons — comma, semicolon, pipe, dash, underscore, or tab — or type in any custom character or string as the replacement.

🔎 Common Use Cases

  • Convert a space-separated word list into a comma-separated list (CSV format)
  • Prepare values for a SQL IN () clause by separating them with commas
  • Turn a space-delimited export into a pipe-delimited format
  • Join words with underscores or dashes to create slugs or variable names
  • Reformat copied data for spreadsheets, scripts, or APIs

⭐ Example

Input:

apple banana cherry grape

Output (with comma separator):

apple,banana,cherry,grape

Output (with pipe separator):

apple|banana|cherry|grape

⚙️ Options Explained

  • Custom separator — Type any character or string to use as the replacement. Default is a comma.
  • Quick presets — Instantly set the separator to comma, semicolon, pipe, dash, underscore, or tab with one click.
  • Collapse multiple spaces — When enabled, two or more consecutive spaces are replaced by a single separator instead of one per space. Ideal for cleaning up texts with irregular spacing.
  • Replace tabs — Also convert tab characters into the chosen separator.
  • Replace line breaks — Convert newline characters into the separator as well, merging lines into one.
  • Trim leading & trailing spaces — Strips spaces at the start and end of each line before replacement, preventing empty leading or trailing separators.

⭐ Real-Time Processing

The tool processes your text instantly as you type. There is no need to press a button — the output updates automatically every time you change the input, the separator, or any option. This makes it easy to experiment with different separators and see the result right away.

⭐ Import & Export

You can upload a .txt or .csv file directly from your computer. After processing, download the result as a TXT or CSV file, or use the Copy button to paste it wherever you need it.
