Hello,
I have an array like this:
`“value”: [{`
`“timeseries”: [{`
`“data”: [`
`{“timeStamp”:“09:15”,“maximum”:45},`
`{“timeStamp”:“09:16”,“maximum”:60},`
`{“timeStamp”:“09:17”,“maximum”:55}`
`]`
`}]`
`}]`
How can I get the Maximum of all the values inside the data array (expected 60)?

Heyy @hktokka Welcome to the community!
You can use this formula to get the max value from your data array.
```auto
{{max(map(9.value[].timeseries[].data; "maximum"))}}
```
Where you can replace the array part with your timeseries array.
I hope this helps!
Best,
@Prem_Patel

Welcome to the Make community!
To do this, you can use these built-in functions:
- **[map](https://help.make.com/array-functions#LkeqT)**
`map(complex array; key; [filter by key]; [csv-values for filtering])`
- **[max](https://help.make.com/math-functions#RAmSm)**
`max([array of values]), max(value1;value2; ...)`
I’d recommend going through the [Make Academy](https://academy.make.com) if you haven’t yet, as these functions have been covered — refer to the [Make Academy Course Overview](https://community.make.com/t/make-academy-course-overview/29699) to learn more.
Here are some useful links and guides you can use to learn more on how to use the Make platform, apps, and app modules. I found these useful when I was learning Make, and hope they might benefit you too —
