What is the first step to run the Document Inspector in Microsoft Excel?

To run the Document Inspector in Microsoft Excel, the first step is to click the Check for Issues button. This button is found within the Review tab and serves as the gateway to various tools related to document quality and integrity, including accessibility checks and compatibility checks. When you click on this button, you will see a submenu that includes options like Document Inspector, allowing you to inspect the workbook for hidden metadata, comments, or any other potentially sensitive information before sharing or finalizing the document.

While it might be tempting to consider actions related to protecting the workbook or saving it, those actions do not initiate the Document Inspector process. The Protect Workbook button focuses on restricting editing and access to the workbook, and the Save As navigation button is strictly for saving the document under a different name or format. Therefore, the Check for Issues button is essential as it directly leads you to the Document Inspector feature, making it the correct first step.
