WPS is a document format: it stores data in the WPS format. XLS is a spreadsheet format that stores data in the XLS format. This extracts structured tabular data from the document into an editable spreadsheet format. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. Converting between these two formats is common when the source application does not support XLS natively or when the target platform only accepts XLS. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
