List to Comma Separated

What is the List to Comma Separated Tool?

The list to comma separated tool instantly converts a vertical column of items — copied straight from Excel, Google Sheets, or any text editor — into a single-line, comma-separated list (CSV). Whether you need to build a SQL IN ('a','b','c') clause, prepare data for an API, or format a tag list, this free comma separator makes the job effortless and error-free.

Instead of manually inserting commas between every item, paste your column on the left and copy a clean, delimited string from the right. The conversion runs entirely in your browser, so your data never leaves your device.

Key Features

• Custom Delimiters: Join with a comma, comma + space, semicolon, tab, pipe, newline, or any custom separator.
• Quote Wrapping: Wrap each item in single quotes, double quotes, backticks, or parentheses — perfect for SQL IN clauses, JSON arrays, and CSV fields.
• Reverse Mode: Split a comma-separated list back into one item per line.
• Smart Cleanup: Trim whitespace, remove empty lines, and deduplicate duplicate items automatically.
• Alphabetical Sort: Sort the list A to Z before joining.
• One-Click Export: Copy to clipboard or download the result as a .txt file.

How to Convert a Column to a Comma Separated List

1. Paste your list: Copy a column of data from a spreadsheet and paste it into the input box — one item per line.
2. Choose a delimiter: Pick a comma (the most common for CSV) or any other separator from the options panel.
3. Optional quotes: Enable quote wrapping if your destination requires it (for example single quotes for a SQL IN clause).
4. Copy the result: Click Copy or Download to grab your ready-to-use comma separated list.

Common Use Cases

• Building SQL WHERE column IN ('value1','value2') queries.
• Preparing CSV data for spreadsheets, CRMs, and email tools.
• Formatting tag, category, or keyword lists for apps and forms.
• Cleaning and normalizing pasted text before further processing.
