About Delimiter Separator

The Delimiter Separator Tool is a free online delimiter converter that helps you change one delimiter format into another in seconds. Convert comma-separated lists, pipe-separated values, tab-delimited text, semicolon-separated data, and custom-delimited content directly in your browser.

Need to convert a CSV list into a pipe-separated list? Turn a newline list into a single line? Change a tab-delimited export for use in a spreadsheet? Simply paste your text, choose your source and target delimiters, and copy the result.

Delimiters are used to separate items in structured text. CSV files use commas, TSV files use tabs, and many databases, APIs, and data-processing tools use pipes (|) or semicolons (;). Editing large lists manually can be slow and error-prone. This delimiter converter automates the process and delivers instant results.

You can also wrap each item in single quotes, double quotes, backticks, or parentheses. Use the output directly in SQL queries. Create Python lists in seconds. Build JavaScript arrays without manual editing. Generate shell arguments from plain text.

Everything runs locally in your browser. Your data never leaves your device, and no account or sign-up is required.

How to Use Delimiter Separator

  1. Paste your list into the input box — one item per line.

  2. Choose a source delimiter (newline is default) and a target delimiter: comma, semicolon, pipe, tab, or type a custom one.

  3. Optionally wrap items in quotes or brackets for SQL, Python, or JavaScript output.

  4. Copy the result from the output panel with one click.

Frequently Asked Questions

Can I join items with a space?

Yes — type a single space in the custom delimiter field and all items will be joined with spaces.

Does it handle blank lines?

Blank lines are automatically filtered out before joining, so your output stays clean.

Can I add quotes around each item?

Yes — select single or double quote in the Quote option to wrap every item like "value" or 'value'. This is useful for SQL IN clauses and Python lists.

How do I create a SQL IN list?

Paste your values one per line, set the delimiter to a comma, select double-quote wrapping, then copy the result. Paste it directly into your SQL IN (...) clause.

Can I convert from comma-separated back to one item per line?

Yes — set the source delimiter to comma and the target delimiter to newline to split a CSV list back into individual lines.

What is the difference between a delimiter and a separator?

The terms are often used interchangeably. A delimiter marks the boundary between items in a sequence. A separator sits between items. Both refer to the same concept in most practical contexts.

Can I use this to build a JavaScript array?

Yes — paste your items, set the delimiter to ", ", add double-quote wrapping, and manually add the surrounding brackets [ and ] to the output.

Is there a limit to how many lines I can process?

No hard limit. The tool runs entirely in your browser and can handle thousands of lines without issues.
