Drop your XLS here
Anywhere on this page works
Turn XLS files into XLSX in this browser tab. Drop the file on the card above, check the output options under it, and download the XLSX as soon as it is ready — there is nothing to install.
No account is needed, nothing is watermarked, and the upload is deleted once your download finishes.
Drop the file in, or pull it from Drive, Dropbox, OneDrive or a URL.
Output is already locked to XLSX. Quality, size and metadata options sit under the card.
Download it straight away. Nothing is watermarked and no account is needed.
Every format we can turn into excel spreadsheet, each on its own page.
XLS does not have to become XLSX. Here is everything else it can be.
