I have purchased the Data Import tool and imported companies and contacts data from csv file using this tool.
Now I want to update a couple of columns with the data which were missing at the time of first import and now available with companies table.
I tried importing 1 company just to check whether the update works if the company already exists, but it inserted a new row.
How can I achieve this as I have to update data for around 2000 companies?
Thanks & Regards
