Column 'Last Name' does not belong to table

Unable to retrieve the Last Name column form a excel spreadsheet. All other columns are read and then entered into a form but for some reason it will not accept the Last Name column. Any thoughts?




Source: Type Into ‘INPUT DcrJd’

Message: Column ‘Last Name’ does not belong to table .

Exception Type: System.ArgumentException

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.ArgumentException: Column ‘Last Name’ does not belong to table .

Check in excel file for the last name column if it has extra space at the end or in the beginning.



Put ColumnName like this [Last Name] and then try.

@jmcentee1488 just check whether you are using the column name which is belongs to that table,if that belongs to that table make sure there are no spaces before the column name in that excel file.

Could you please share xaml and Excel file with me. Will check and update you.

Try this …first read the excel sheet then in for each try Datatable.Columns and after that display item in log or msgBox. It will show all the columns name available in you Excel Sheet.

Hi @jmcentee1488

Welcome to UiPath community

Fine we can either mention with column index in the type into field as input
Like this
Where 1 index mention the column Last Name and usually the column index starts with 0

Or to find the column name exactly
Use simply a write line like this
This will print the column name of that column in write line Activity…
Well we can use that…

Hope this would help you
Cheers @jmcentee1488


Thank you. row(1).ToString worked.

Where do you think the issue is with the column name? is it with Excel or UIPath?



If row(1) worked then the table has read in fine so the only issue could have been:

  1. You didn’t read the table in with headers enabled in properties
  2. The column header is not “Last Name” and either contains spaces at the start or end or maybe a newline after Last to split it onto two lines

Fine lets check what is the name of that column using a write line activity
–put this in the write line activity that would output the column name in the output panel
to check the length of the columnname
actually it should be 9
check whether it is 9 or not
we will come to know the issue buddy
Cheers @jmcentee1488

any issues still buddy
Cheers @jmcentee1488


I went with row(1).ToString and that seem fairly stable. I still am trying to understand why it does not see the colname “Last Name”… As you can imagine this issue could pop up other places and I need to understand cause.

Fine @jmcentee1488
There can 2 reasons buddy

  1. either the column name must have space in front or at back to name “Last Name”
    like this " Last Name" or "Last Name ", which might not let the bot to the recognize the column name
  2. The term Last Name must of two lines either, i hope it wont be but this can be checked only with this buddy
    where here 1 denotes the column “Last Name”, we can check by just writing this in write line activity to check the actual issue, which would surely help us to solve the issue

Thats all buddy, these things must be the reason…else would be fine
Cheers @jmcentee1488

Yes, Write Line gave me “Last Name” in the output.

if possible can i have a screenshot of the write line output, just to check whether any space occurs or not
Cheers @jmcentee1488

I still wonder why it didn’t
fine lets check the length of the string “Last Name” and it should be 9
Try with this buddy @jmcentee1488

It will not let me covert int to TS.
