## convert sp list column of strings to integers, and find highest integer

I need my flow to perform what the title says. My entire column of values in my sharepoint list are strings, so i thought that int() would be appropriate, but im struggling to figure out how to actually use the function. And then Ill need to maybe add all my integers to an array and find the highest value?

Any help would be massively appreciated.

Below is how I'd write the flow to get the largest number.

For this example, I'm using the following list of numbers (as text). The result in this instance should be 123.

See full flow below. I'll go into each of the actions.

Get items will retrieve your items. Note that by default Get items will only get the first 100 items in the list. If you have more than this, you can set the Top Count to a number up to 5000 (max) so it will retrieve up to 5000 items. If you have more than 5000 items, then let us know and we can show you how to set Pagination and a Threshold.

Select extracts out each of the numbers and converts them to float. We could also convert them to int if there weren't any numbers with decimal places. In this example, I'll assume that we could potentially have numbers such as 3.2, 5.0, etc. The expression used to convert each of the numbers from string to float is below. The expression also uses coalesce which will default any empty values to 0 so we don't get an error when trying to convert them.

``````//coalesce will default any empty values to 0 so we don't get an error
float(coalesce(item()?['Title'], 0))``````

Compose uses the following expression to sort the numbers in ascending order and get the last item (the largest number).

``````//Sort the numbers in ascending order, then get the last (largest) number
last(sort(body('Select')))``````

After running the flow, our Compose output would be.

Hi @Papgooner ,

Here is flow:

Take out a column by [Select] to form an array

Define the first number in the array as the value of the largest variable

[Apply to each] traverse the array, and use the number greater than the value of the current variable to redefine the variable
