Hi @Yuyu33
In the filter array expression - you have to convert the dates on both sides of comparision to single format - let's say yyyy-MM-dd for this case.
so expression would be
Left side > formatDateTime(item()?['Date_de_modification'],'yyyy-MM-dd')
Right side > formatDateTime(utcNow(),'yyyy-MM-dd')
Another easy approach would be as suggested by @AndiM using Odata Filter query
You can use Odata filter query and then you can use select action with whichever details/columns you need , that would be more efficient.
Filter query Odata should be like this -

(Modified ge '@{formatDateTime(utcNow(),'yyyy-MM-dd')}') and (Modified le '@{addMinutes(addDays(formatDateTime(utcNow(),'yyyy-MM-dd'),1),-1)}')
What i understood is Modifed column is your Date_de_modification column , so why don't do a filter first with odata using modified date and then do a further select actions ?
Try this and let me know 🙂
