Convert between column data (one item per line) and delimited data (e.g. comma-separated). Customize delimiter, quotes, tags, and more.
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.
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.
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.
No. All conversion runs in your browser. Your data is never uploaded or stored on our servers.
Yes. In Converter settings, set the delimiter to any character or short string (e.g. semicolon, tab, or pipe).
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.
