Free Go Library for Converting Microsoft® Spreadsheet Files

Convert Microsoft Excel XLSX and XLS Spreadsheet Documents to PDF via Open Source Go API  

By using the open-source Gotenberg Go client library Go developers can easily convert Excel documents to PDF in their own applications. Using the API, you can convert XLS, XLSX, and ODS file format to PDF easily. The API allows converting one or more files at the same time, and all the files are merged into a single PDF file. Furthermore, the API merges the documents alphabetically.

By default, the resultant PDF document will be rendered with portrait orientation but the API allows customizing the orientation. By default, a handful of fonts are installed. Asian characters are also supported out of the box. Furthermore, you can set page numbers and timeout for the conversion process.
