Formatting JSON Attribute in ArcGIS Online Pop-ups

Shelley_Broadway — Mon, 10 Oct 2022 19:03:30 GMT

Is there a way to format JSON in an attribute column so that it's easier to read in the map pop-ups? For example, one of the fields in my data contains JSON --

[{"Data_ID":"XXXXXXX","FormDataID":"YYYYYYY","FID":"Lines_p2.atyo12lfi98009938809876344560","Owner":"Example","Material_Type":"P ","Size":"7","Misc_Notes":null,"Permit_No":null}]

I want to pull out Owner, Material, and Size and show in the pop-up. Can this be done with Arcade?

Yep

Create a variable using your $feature.FieldName, then call out the bits in whatever format you want.

var json= {"Data_ID":"XXXXXXX","FormDataID":"YYYYYYY", "FID":"Lines_p2.atyo12lfi98009938809876344560", "Owner":"Example","Material_Type":"P ","Size":"7", "Misc_Notes":null,"Permit_No":null} return 'Owner: ' + json.Owner + textformatting.newline + 'Material: ' + json.Material_Type + textformatting.newline + 'Size: ' + json.Size

I think I'm missing something here. I was able to create a valid expression, but all my pop ups are the same with the values from the var json line appearing in the pop up not the value from the attribute table.
