Is it true that Microsoft Excel needs to be installed to use the 'Get Cell Color' activity?

The statement that Microsoft Excel needs to be installed to use the 'Get Cell Color' activity is accurate because this activity relies on the Excel application to access and manipulate the contents of an Excel file, including the color of specific cells. The 'Get Cell Color' activity is designed to interact directly with Excel, which means that an active installation of the software is necessary for the activity to function properly. When the RPA tool calls this activity, it depends on the Excel API to retrieve the color properties of cells, which would not be possible without the Excel application being present. This integration is crucial for enabling the automation of tasks that involve reading or modifying Excel data.

Other forms of data extraction or manipulation without Excel might be possible using different methods or activities, but for specifically obtaining the color of a cell within an Excel sheet, having Excel installed is essential.
