RAR to XLSX: Convert an Archived Excel Workbook

A RAR archive is often how a spreadsheet arrives by email or download, because compression makes the transfer smaller. Excel will not read the container itself, so the workbook cannot be used until the archive is opened.

XLSX is the current Excel workbook format, understood by Excel, LibreOffice Calc, Google Sheets and most reporting tools. Producing XLSX returns the rows and columns to a form that a spreadsheet program can calculate with.

GroupDocs.Conversion Cloud takes the archive over a REST endpoint and returns the workbook. Select all of the content or a chosen range of pages, decide the output quality, mark the sheet with a watermark, and require a password before the download begins.

Each call is signed with a Client ID and a Secret, and cURL examples cover upload, conversion and download in three requests. A free trial is available, the browser converter handles a one-off file, and the API Explorer repeats the request interactively.
