I have spent too long trying to figure this out.
I have a sharepoint column containing a signature from Plumsail Forms.
When I try to put the field into the JSON formatting the output is - "data:image/png;base64,iVBORw0K
When I try and use base64('Field Name') into the JSON formatting the output is - NXlvSUlIRUZBQWVGbEE2SkxzQ3lkd1o0W
How can get the signature into the word document?
