max() value of a column

Is there a way to use max() to grab the maximum value from a column? 

 

I am using the Excel connector and the "List rows present in a table" block.

 

I am hoping for something like this:

max(body('ListRowsPresentInATable')?['Key'])

 

Otherwise, I guess I'll loop through the keys and append them to an array variable and max that, but the above approach would be quicker.

 

Thank you for your assistance.

Hi @BenDonahue 

 

Read the Excel Rows first. Use the Select action to get all the keys. This will return the array. Then use the max() expression for the array to get the number.

 

Thanks

Above expression is as follows:

 

outputs('List_rows_present_in_a_table')?['body/value'][0]?['Age']

 

Thanks

@abm ,

Thank you for your help.

Can I impose for a bit more help, please?

I set up the Select block like this:

Then tried to max Key column. This feels like the same issue I had to begin with.

 

I tried not using a Key column in Select and maxing the outputs, but no luck with that either.

 

1. Am I using the Select block correctly?

2. What is the syntax in the following Compose block?

 

Thank you, again, for your help, abm.
