Excel: compare tables and find differences (letters not numbers)

I am looking for a freelancer who can help me compare two tables in Excel that include both alpha and numeric data. The purpose of this comparison is to create a new table based on the comparison results. I will need the ability to compare multiple tables as well. The freelancer should be an expert with Excel and be able to handle this task efficiently. Any advice or tips regarding best practices for this type of project would be greatly appreciated. Please provide examples of past work and a timeframe for completion. Thank you for your time. I have two Excel spreadsheets with values ​​such as web addresses. In Table 1 is the data to keep. The spelling is different: [login to view URL] or [login to view URL] Table two contains data to be added to table 1. It should now be checked automatically whether the data in Table 2 is already in Table 1. Example: Table 2: Cell A1: [login to view URL] Cell A2: [login to view URL] Cell A3: [login to view URL] Table 1: [login to view URL] [login to view URL] [login to view URL] .... So in this example, the contents of cell A2 would already be in Sheet 1. Therefore, the contents of cell A2 in Table 2 should be highlighted. The query should run automatically. If new cells are added to Table 2, they should be checked and marked if necessary. Is this possible? For example via Power Query or something?
