Prerequisite

Steps to Convert XLSX to PDF with NET REST API

  1. Set the Client ID and Client Secret for the API to convert XLSX to PDF
  2. Create an instance of CellsApi class with client credentials to perform XLSX to PDF conversion
  3. Specify the source XLSX and output PDF file names and load the source XLSX file in a memory stream
  4. Create an instance of the PostConvertWorkbookToPDFRequest with input XLSX file stream and other optional parameters
  5. Call the XLSX to PDF request method to convert XLSX to PDF with NET REST API
  6. Save the rendered PDF file stream on the local disk

The above mentioned steps entails the transformation of the file type from XLSX to PDF with c# low code API. We will start the process with the configuration of the SDK and creating the CellsAPI class object. We will load the source XLSX file using a FileStream and create an instance of the PostConvertWorkbookToPDFRequest class that is further used for performing the conversion to a PDF file stream using the PostConvertWorkbookToPDF() method.
