What’s the source of the DataTable? if it’s from Excel file then while reading it using Read Range activity, check the Preserve format checkbox.
It seems the Datatable contains the data in Double then while serializing it’s being passed as double but when we deserialize it, it’s not able to read few data to Double.
I would suggest to check the DataTable source for incorrect datatype.
please use the </> format button from editor when sharing snippets or share it additional as text file
check in the datatable in which column the 11-222-33 is present and what other values are present
we assume: unrealizing = deserializing
due the fact that the first row is used for the data column datatype calculation is used a lter occuring string 11-222-33 will conflict as it is not a double
