[zheng-yifan]

Hi ! @Allan_Zimmermann ,
I wan’t to use ReadJSON to read json file,file like “{“name”:“test”}”.error like pic

i wan’t know how to write DataTTable.
thank you.

[Allan_Zimmermann]

you need to create a datatable variable and use it with the activity

thanks,i wan.t know the [DataTtable] type.what need i write .

[zheng-yifan]

i try write lik pic.it’s error.what need i change.

[Allan_Zimmermann]

Click on the variable’s tab

then you can create the variable there, and then use that variable in ReadJSON.
Create datatable is used to CREATE one, but you don’t need to create one as ReadJSON will do that for you.

thanks,but also have error.mabe my json file is error.
rpa setting like pic1

json file like pic2

[Allan_Zimmermann]

That is not valid json, you need to escape the string ( use two \ instead of one )
