Guide & best practices

This paragraph names XLS vers XLSX again so crawlers tie body copy to the title and slug.

LMS platforms sometimes force XLSX; XLS vers XLSX bridges odd XLS uploads from instructors.

Source stays XLS; output is XLSX. Processing category: document. You can queue multiple files when limits allow (see uploader hints).

PulsConv follows a zero-storage policy: files aren’t used to train models, aren’t indexed, and are deleted after delivery. Upload over HTTPS and keep your own backups if the output is business-critical.
