How to Use the Comma Separator

Paste your data in either panel: column data (one item per line) or delimited data (e.g. comma-separated). Use the settings to choose how to split column data, which delimiter to use, and whether to add quotes, tags, or interval wrapping. Click the right arrow to convert column → delimited, or the left arrow to convert delimited → column.

  1. Paste column data (one item per line) in the left panel, or delimited data in the right panel.
  2. Open Converter settings and set Split by (newline, space, comma, semicolon), Delimiter, and optional Quotes or Tags.
  3. Use To delimited (→) to turn column data into a single line (or multiple lines if interval is set). Use To column (←) to split delimited data into one item per line.
  4. Enable Remove duplicates, Sort, or Reverse if needed. Use Prefix and Suffix to add text to each record.
  5. Copy or download the result from either panel. All processing runs in your browser; nothing is sent to a server.

When to Use This Tool

Common use cases for converting between column and delimited data:

  • CSV / spreadsheets: Turn a list of values into a comma-separated line for CSV, or split a CSV line into a list.

  • Lists and bullets: Convert a list into comma-separated form or wrap each line in <li> tags for HTML.

  • HTML or XML: Use open/close tags to wrap each record (e.g. <li>…</li>) or interval wrap (e.g. <ul>…</ul>) for grouped output.

  • Bulk data: Trim, sort, remove duplicates, and add prefix/suffix to clean and format pasted data.

Frequently Asked Questions

What is a comma separator tool?

It converts between column-style data (one value per line) and delimited data (values separated by a character, usually a comma). You can add quotes, HTML tags, sort, remove duplicates, and set a custom delimiter.

Is my data sent to a server?

No. All conversion runs in your browser. Your data is never uploaded or stored on our servers.

Can I use a delimiter other than a comma?

Yes. In Converter settings, set the delimiter to any character or short string (e.g. semicolon, tab, or pipe).

What are interval and interval wrap?

Interval adds a new line every N records. Interval wrap lets you wrap each group in tags (e.g. every 3 items wrapped in '<'ul>…'<'/ul>), useful for HTML lists.
