Free Online Delimiter & Comma Separator Tool

Welcome to the ultimate Delimiter and Comma Separator Tool. If you regularly work with data, spreadsheets, or code, you know how tedious it can be to manually format lists. This tool serves as the perfect delim.co alternative, allowing you to instantly convert vertical columns into comma-separated lists, and reverse the process with a single click.

How Does the Column to Comma Converter Work?

Using this web utility is fast, secure, and intuitive:

• Column to List (►): Paste your data from Excel, Word, or Google Sheets into the left text box. Select your desired delimiter (comma, semicolon, pipe) and click the right arrow to merge everything into one horizontal string.
• List to Column (◄): Have a messy, unformatted block of CSV data? Paste it in the left box, click the left arrow, and watch the tool split the delimited string back into a clean vertical list.

Advanced Features & Settings

Unlike basic comma inserters, this tool provides advanced settings for database administrators (DBAs), developers, and digital marketers:

• Custom Delimiters: Don't want a comma? Separate your values with semicolons, pipes, spaces, or any custom character you type into the settings box.
• SQL & JSON Quotes: Instantly wrap your data in single quotes ('item1', 'item2') for SQL IN() queries or double quotes for JSON arrays.
• Data Cleaning: Automatically remove duplicate entries, strip out empty blank lines, and trim invisible whitespaces from your raw data before processing.

100% Secure & Private

Your privacy is our priority. This entire delimiter tool is powered by client-side JavaScript. This means your data is processed entirely inside your web browser. We do not store, track, or upload your sensitive email lists, queries, or database dumps to any external servers.
