Common questions
How do I convert a CSV file to Excel?
Upload or drag your .csv file into the converter above. It's parsed in your browser and turned into a downloadable .xlsx file — no software or account needed.
Is csvtoexcel.io free to use?
Yes. Converting CSV to Excel here is free, with no sign-up or file limits for typical use.
Does csvtoexcel.io upload my file to a server?
No. Conversion happens entirely in your browser using JavaScript. Your CSV data is never transmitted or stored anywhere.
Why does my CSV look wrong when I open it in Excel?
Usually it's character encoding, the wrong delimiter for your region, or numbers being misread as dates. Converting to a proper .xlsx file avoids all of that. Read more in our guide.
