Steps to Reset XLSX file Password using NET low code API

  1. Set the Client ID and Client Secret for the API to decrypt the Workbook with a password using NET REST API
  2. Create an object of the CellsApi class with client credentials to reset XLSX file password using NET low code API
  3. Add the source XLSX file names and load the source XLSX using a name and File object in a HashMap
  4. Create an instance of the DeleteUnProtectWorkbookRequest to add the existing password and other properties
  5. Call the DeleteUnProtectWorkbook request method to decrypt excel file with password using NET REST API
  6. Save the decrypted XLSX file/s on the local disk

The aforementioned steps remove password protection on XLSX using NET REST API. We will initiate the process with the setting up the SDK and creating the CellsAPI class instance. We will then load the source XLSX file/s using a HashMap and create an instance of the DeleteUnProtectWorkbookRequest class that is further used for resetting the password protection for the XLSX files using the deleteUnProtectWorkbook() method.

Code to Decrypt XLSX file Password using NET REST API

This simple example code enables you to clear excel file password using NET low code API.
