Convert CSV to Excel
Save a CSV as a proper .xlsx workbook. Numbers are stored as numbers, so you can sum and sort them as soon as the file opens in Excel.
How to use it
- Drop in a .csv file or paste the rows.
- Check the preview and the options.
- Click Download to save the .xlsx file.
Questions
Why not just open the CSV in Excel?
Excel guesses how a CSV is laid out and often guesses wrong. A file separated by semicolons can end up in a single column, and long ID numbers get rounded. Converting first avoids both problems.
Will long ID numbers be kept exactly?
Yes. Numbers longer than 15 digits and values with leading zeros are stored as text, so Excel will not round them or show them in scientific notation.
Do my files get uploaded?
No. The page does the work inside your browser, and your files are never sent to a server. That makes it fine to use with private documents such as contracts or bank statements.
