Find Answers to AWS Questions about Amazon Macie | AWS re:Post

So I have started using the Macie service to do some data classification for a project I am building. I originally tried it with some JSON data that was put into a text file that contained US SSN numbers. I ran the Macie service to have it try and find this data and the scan did not return any findings.

Next I figured that I would try the Macie scan on a an excel file with three columns. The first column had 5 first names, the second column had 5 last names, and the third column had 5 SSN numbers. Nothing else was in the excel file. I ran the Macie scan again and it still failed to find any sensitive data. I tried using the all managed identifiers scan and just the individual SSN scan and neither of them returned any findings.

Does anyone know what I might be doing wrong and why Macie cant find simple SSN numbers? I am happy to provide more context as well as share the files if it will be helpful (all the SSNs are fake numbers for testing).
