CSV Delimiter Converter
Convert a CSV between different delimiters — commas, tabs, semicolons and more.
Not all CSVs use commas
Despite the name, comma-separated files do not always use commas — semicolons, tabs and other characters are common separators too. This converts a file between delimiters, so data separated one way becomes separated another.
Load your file and choose the source and target delimiters.
Why the delimiter varies
The delimiter varies for genuine reasons. In regions where the comma is used as a decimal separator in numbers, semicolons are commonly used to separate CSV fields instead, to avoid clashing with the commas inside numbers — which is why a CSV from such a locale can look wrong when opened expecting commas. Tabs are another common separator, giving tab-separated values. A program expecting one delimiter will misread a file using another, cramming everything into one column or splitting it wrongly, which is a frequent source of import headaches. Converting to the delimiter the receiving program expects fixes it cleanly. This is a routine need whenever data moves between tools, regions or systems that assume different separators, and getting the delimiter right is often the difference between a file importing perfectly and importing as a mangled mess.
Common questions
Why don't all CSVs use commas?
In regions where the comma is a decimal separator, semicolons are used to avoid clashing with numbers, and tabs are also common — so the separator varies.
What happens if the delimiter is wrong?
The program misreads the file, cramming everything into one column or splitting it wrongly — converting to the expected delimiter fixes it.
