About DataTable Instances

Japan Forum

I am a user of UiPath Studio 2025.0.197STS Community edition.
I am developing with modern design.

I know that when reading ranges from Excel or generating a DataTable from a text file, the programmer does not need to create a DataTable instance manually. However, if I write New DataTable() in the default value of the DataTable variable in the variables panel (which is originally unnecessary), will it create two DataTable instances, or just one?

Incase you initialise the variable with New Datatable() and then assign another Datatable using read range or any other way. The variables initial value will be replaced or overwritten. It won’t create two instances.
