When I am executing the Excel node, I am getting the error as "Process exited with error...class not registered...". Image description

This error occurs when you do not have licensed Microsoft Excel installed on the bot machine you are executing the excel node. Install Microsoft Excel and rerun the task.
If licensed and the error persists, check if it is activated and logged in with the right credentials.

When trying to open an excel file using the excel node, I am getting a popup “We can’t update some of the links in your workbook right now….” I am unable to proceed until the Continue button is clicked, because of which excel automation fails. Image description

To suppress the message and to automatically update the links, follow these steps:

  1. In Excel, select File > Options > Advanced.
  2. Under General, clear the Ask to update automatic links check-box.

Tasks are failing due to permission issues while opening the files. Image description

Check if the folder that is used has required permissions. If not, provide full control access to the bot user.
Perform the following steps to provide full access.

  1. Go to the Properties of the folder that you are using.
  2. Navigate to the Security tab.
  3. Select the user and click the Edit button.
  4. Check the Full control checkbox and click the Apply button.
