Appending excel

Hi,

 

I am trying to append almost 200 excel files, but I keep getting the error below. (Expression error) The key didn't match any rows in the table. It provides no other info, so I am not sure what to change. What am I missing to be able to combine the files if they are all formatted the same?

are those files exported from a certain system ? have they ever been opened ?

the reason I am asking is that some systems when an excel is exported they have a corrupted xml schema

 

if the above is the case, then I recommend on of the below solutions:

1- export csv files instead of the excel files

2- open each excel file and save without change. this will allow excel to repair the xml schema

 

then retry the append operation

 

Did my reply help you to solve the problem? If yes, please accept my reply as the solution 🙂
