Privacy and processing
What happens to my XLSB?
XLSB files up to 5 MB are read and converted inside your browser using the local Web Worker flow. They are not sent to our server. Larger XLSB files are uploaded directly to private temporary Blob storage, converted on the server, and then the temporary source file is deleted as part of the conversion cleanup flow.
