What this tool helps you do
Adapt a CSV export to an application that expects a different separator. Choose the actual input delimiter and the required output delimiter. The parser reads quoted cells before rewriting separators, so a semicolon inside a quoted value remains data rather than becoming an extra column. Leading zeroes, empty cells and embedded line breaks are retained as text.
Format rules and limitations
This does not guess the separator, infer headers or convert numeric formats. Rows must be rectangular and the table must stay within fifty thousand cells. Output uses CRLF record endings and quotes values where the chosen separator or a line break requires it. Optional BOM output can help some spreadsheet importers identify UTF-8. It does not convert the file into a legacy character set; use the separate encoding converter for that.
Example input
id;name;note 001;Ada;"one;two"

Is input uploaded?
This tool sends input to this site’s conversion API after you select Convert on server. Files use bounded workers and, when needed, private temporary folders deleted after processing or cancellation. No conversion history is saved. The converter does not upload files to a third-party conversion service.
