I have data in the form:
col1 col2 col3
A X data
A Y data
A Z data
B U data
B V data
B w data
and I want to make multiple files based on the values of col1 and inside each file, the tabs should be named after the values in col2. The data should correspond to the entries associated with col2 values. My current method gives this output error "Output Data (45) sheetname is an invalid Sheet/Range specification for Excel". Please help in rectifying this.
