    LON,

    Change your code as follows. And maybe you would need to change List.IsEmpty(content) part in the following code to List.IsEmpty(Source) or List.IsEmpty(body), you can test it.

    let

Source = Json.Document(Web.Contents("https://xxxxxxxxxxxxx", [Headers=[zzzzz="xxxxxx"]])),
body = Source[body],
content = body[content],
#"Converted to Table" = Table.FromList(content, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
Table1=Table.FromRecords({
        [Column1 = ""]
        
    }),
     result= if List.IsEmpty(content) then Table1 else #"Converted to Table" 
in
     result

Hi Lydia

 

Just a follow up question please - I tested that and it worked perfectly thanks with the #"Converted to Table".   Im just a bit stuck in trying to include a second statement where I expand the Table - basically how to put multiple statements in the if .. then.. else statement?

 

#"Converted to Table" = Table.FromList(content, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table", "Column1",

 

Best Regards
