    Hi david2,

     

    After looking into the pbix file and JSON files you shared with me, I found several issues you may need to pay attention to.

     

    1. Use formula below in your Advanced Editor.

        #"Renamed Columns" = Table.RenameColumns(#"Expanded Column1",Table.ToRows(fields))
in
    #"Renamed Columns"

    Not

        #"Renamed Columns" = Table.RenameColumns(#"Converted to Table",Table.ToRows(fields))
in
    #"Renamed Columns"

    2. As a table cannot have two columns with the same column name, please make sure all values of "name" column in "fields" table are unique and not already exist in "deals" table.

     

    Here are the modified pbix file and JSON files for your reference.

     

    Regards

Hi david2,

 

Could you go and check if there is any blank spaces within the column name of  "title" in pipdriveDeals(like "title    ").

Hi v-ljerr-msft

 

There's no space in the "title" column in pipedriveDeals nor the row in the pipedriveFields table. I deleted this line from the table to see if the script works with another one of the columns, but unfortunately still get the same problem.

 

I've also tried to make the column with keys in the pipedriveFields table a string, but that also doesnt work.

 

What are the conditions for the Table.RenameColumns and Table.ToRows functions to work properly?

 

  • I assume the list of columns in pipedriveFields should exactly match the list of rows in the pipedriveFields table
  • The list of keys (that matches the column headers in pipedriveFields) should be in the first column of pipedriveFields
  • Anything else?

 

Any other ideas on this one? Thanks :-)

    I don't think there are any other conditions for the formula to work. I went to test it again on my side and it worked all fine for me. Could you share a sample pbix file which can reproduce the issue in your case? You can upload it to OneDrive or Dropbox, and send me the link in private message. Do mask sensitive data before uploading.:smileyhappy:
