Versatile Delimiter & List Formatting
Every professional works with lists: email addresses, product SKUs, tags, IP addresses, zip codes, and code identifiers. Frequently, data from one software (like Excel or a log file) must be formatted with commas, quotes, or custom separators for another tool (like an email campaign or database query).
FixMyString Delimiter Converter effortlessly transitions text between columns, commas, quotes, and custom delimiters in real time.

Frequently Asked Questions
What does the List & Delimiter Converter do?
It converts lists and data between different separators — such as turning a vertical column of values from Excel into a comma-separated list, changing semicolons to pipes, or wrapping every item in quotation marks.
Can I convert a column copied from Excel into a comma-separated list?
Yes! Simply paste your column from Excel, and choose "Comma (,)" as your target delimiter. You can also automatically wrap items with quotes.
Can I add custom prefixes and suffixes to each item?
Yes. Use the Item Prefix and Suffix fields. For instance, prefixing with "- " turns lines into a Markdown bullet list, or prefixing with "<li>" and suffixing with "</li>" produces HTML list items.
Can I change comma-separated text back into vertical lines?
Yes! Click the "Comma → Column" preset button or set Output Delimiter to "Newline".
Does it remove duplicate entries?
Yes. Checking "Remove duplicates" eliminates redundant entries so your resulting list only contains unique elements.
Is my data processed locally?
Completely locally. The transformation runs 100% in your browser using JavaScript. No information is stored or transmitted.
Can I specify a custom delimiter?
Yes. Select "Custom" for either input or output delimiter to specify custom separators such as " AND ", " OR ", " / ", or tabs.
