I'm doing the following calculation.
worksheet.write_formula('E5', '=({} - A2)'.format(number))
I want to print the value in E5 on the console. Can you help me to do it? Is it possible to do it with Xlsxwriter or should I use a different library to the same?
It is not possible to read data from an Excel file using XlsxWriter.
There are some alternatives listed in the documentation.
Not answering this specific question, just a suggestion - simply try pandas and read data from excel. Thereafter you can simply manipulate the data using pandas DataFrame built-in methods:
df = pd.read_excel(file_,index_col=None, header=0)
df is the pandas.DataFrame, just go through DataFrame from this it's cookbook site. If you are unaware about this package, you might get surprised by this awesome python module.
