THE PROBLEM
How do I change the delimiter in a CSV file?
Regional Excel settings and different import systems may expect semicolons, tabs, pipes, or commas. A simple find-and-replace can corrupt values that contain separators inside quotes.
- Cell values, row order, column order, and quoted line breaks are preserved.
- The tool does not clean duplicates, whitespace, or malformed quoting.
- The source file is not modified.
HOW IT WORKS
Clear changes, no hidden guesses
Quoted separators are data
A comma inside a quoted address stays inside that cell instead of becoming a new column.
Regional CSV formats
Semicolon CSV is common where commas are used as decimal separators; tab-separated files are common for bulk imports.

Confirm the detected columns before converting, especially when a file contains only one data row.
