Password Protect Excel File using NET REST API

In this simple topic, you’ll learn how to convert XLS to PNG with NET REST API. We will develop an XLS to PNG converter with C# Low Code API by following the detailed and lucid steps mentioned in the following section. The developed application can be integrated with any .NET application supported in macOS, Linux, or Windows environments and conversion can be done for free.

Prerequisite

Steps to Convert XLS to PNG with NET REST API

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

The aforementioned steps transform the file type from Excel to PNG with C# low code API. We will start the process with the initialization by configuring the SDK and creating the CellsAPI class object. We will then access the source XLS file using a FileStream and create an instance of the PutConvertWorkbookRequest class that is further used for performing the conversion to a PNG file stream using the PutConvertWorkbook() method.
