I got a problem while i was working in the uipath.
Writing in a excel sheet displays an error message " Object reference not set to an instance of an object "
what is the solution for this error?
The item which you are writing is Null or empty, please check the values before you are writing.
This means that there is no data in the table or it has not been initialized before writing into the excel. Do make sure that you have data in datatable.
Write a check if DataTable.Rows.Count>0 then only it should proceed
i have already some datas in the sheet
attach your workflow, lets see!
You have some data in the sheet , but you should check that you are having any data in data table .
Before write range put log message and write datatable.rows.count.tostring
And initialise the datatable means take one assign activity in the beginning of your flow .
Assign yourdatatable = new data table
Implement this , if still not working , upload your workflow.
