The XCO library offers classes (`XCO_CP_XLSX` and others) and methods for reading and writing XLSX content. You can find more information [here](https://help.sap.com/docs/btp/sap-business-technology-platform/xlsx). The following example demonstrates a selection of methods and includes the following steps:
- Importing an existing XLSX content into your SAP BTP ABAP Environment system (not related to the XCO library; just to have content to work with in the self-contained example below)
- Importing existing XLSX content into your SAP BTP ABAP Environment system (not related to the XCO library; just to have content to work with in the self-contained example below)
- This is a simplified, nonsemantic, and explorative RAP example (not delving into RAP as such; just using various ABAP repository objects related to RAP) solely for importing XLSX content to work with in the example.
- ⚠️ Note the repository's readme file for disclaimer and the [documentation](https://help.sap.com/docs/btp/sap-business-technology-platform/xlsx-read-access) for security considerations when importing and processing external content.
- The import is done using an automatically created SAP Fiori Elements app preview, which provides a simple UI for uploading local XLSX content.
