Cannot convert a value of type Record to type Text.

[JohnLow]

Hi,

I'm currently trying to extract values from a list column, called data.custom_fields which has 9 records. However I'm getting the following error message:

Expression.Error: We cannot convert a value of type Record to type Text.

Details:
Value=
compulsory_on_complete=FALSE
name=Staff Member
value=
value_id=
type=choice
id=1
visible_to_staff_only=TRUE
Type=[Type]

My M Code is as follows:

Any help, much appreciated.

Thanks

The Text.Combine function in your last step expects a list an the input, but it looks like you have expanded a list of records. You should be able to expand that column of [Record] values. Have you tried that (instead of using Text.Combine)?

Yes, but if I expand this, it give me 9 rows for each record and I would like 9 columns instead. Just not sure how to do that.

Hi @JohnLow ,

Please refer to the following steps, hope it helps.

let
    Source = #table({"aa","bb"},{{1,{1,2,3}},{2,{33,44}}}),
    Custom1 = Table.TransformColumns(Source,{"bb", each Record.FromList(_,{"1"..Text.From(List.Count(_))})}),
    #"Expanded bb" = Table.ExpandRecordColumn(Custom1, "bb", {"1", "2", "3"}, {"1", "2", "3"})
in
    #"Expanded bb"
