IsEmpty function in sharepoint list/ form

Question

Hi,
I have a modern SPO list with text columns A, B, C. I want to show only Column B if A is not empty, and show Column C if B is not empty. Can someone please advise the JSON formula for this?

Thanks.

You could follow below steps to hide a column in the list new form.

1.+New -> In the upper right corner of the form, click -> Edit columns.

2.Navigate to the desired column for which you want to set a conditional formula -> Select the far right hand edge of the column name to display the options menu (...) -> Edit conditional formula.

3.In the column B, =if([$A]=='','false', 'true'). In the column C, =if([$B]=='','false', 'true').
