CSV to Excel
Turn a CSV into an Excel (.xlsx) file with properly separated columns and numbers recognised as numbers, including decimal commas.
Why a CSV opens badly in Excel
In Spain, Excel expects the semicolon as a separator and the comma as the decimal mark. If the CSV comes from another program using commas as separators, or with a different encoding, everything ends up in one column or with broken accents.
This converter detects the separator, reads the file as UTF-8 or Windows-1252 and produces a real .xlsx, with each value in its own cell. Amounts with a decimal comma (for example 1.234,56) are turned into numbers, so you can sum them straight away.
How to use it
- Load the file or paste its content.
- Check the preview and adjust the separator if needed.
- Download the Excel file.
Everything happens in your browser: the file is not uploaded to any server.
Frequently asked questions
How do I convert a semicolon-separated CSV to Excel?
Load or paste it here. The separator is detected automatically and the result is an .xlsx file with each column in place.
Do numbers with a decimal comma work?
Yes. With “Recognise numbers” on, 1.234,56 is saved as the number 1234.56 rather than as text.
What if accents come out broken?
The converter tries UTF-8 and, if it detects wrong characters, reads the file as Windows-1252, the usual encoding of older business software.
Is my file uploaded?
No. It is converted in your browser and does not leave your computer.
