Append to CSV with datatable with null values



I have a data table, and some cells do not have a value (so I think they are null values). I wish to append that data table (with cells that do not have values) to another CSV, but I keep getting an error (“Error: Object reference not set to an instance of an object”).

Any advice? Can a data table with null values be appended to CSV in the first place? Thanks.


lease upload your input csv and output (expected output) csv :slight_smile:


Hi @iceicecreme,

There should not be any problem with null values in the datatable. Here is an example (2.0 KB)

As @rahatadi suggested, uploading your input csv would be helpful.

Best Regards,
