https://community.blueprism.com/t5/Product-Forum/Set-Column-Names-of-Excel-dynamically/m-p/70821#M23426 Hi, I would like to change column names in excel dynamically. Iteration through row seams to be easy but columns in Excel start with alphabet letters. I changed reference style for R1C1 in Excel and in set cell value action (MS Excel VBO) in cell reference I input expression: "R1C"&[CounterDate]&"" I am getting following error from this stage: Exception from HRESULT: 0x800A03EC Could you help?
