How to extract sheet from *.xlsm and save it as *.csv in Python?


I have a *.xlsm file which has 20 sheets in it. I want to save few sheets as *.csv (formatting loss is fine) individually. Already tried xlrd-xlwt and win32com libraries but could not get through. Can anybody please provide a code snippet which does the above processing in Python? I have other python dependencies so no other language would work. Thanks


Solution

  • xlrd should work fine on xlsm files as well. I tested the code with a random xlsm file, and it worked perfectly.

    import csv
    import xlrd
    
    workbook = xlrd.open_workbook('test.xlsx')
    for sheet in workbook.sheets():
        with open('{}.csv'.format(sheet.name), 'wb') as f:
            writer = csv.writer(f)
            writer.writerows(sheet.row_values(row) for row in range(sheet.nrows))
    

    If you've encoding issues, try the code below:

    import csv
    import xlrd
    
    workbook = xlrd.open_workbook('test.xlsm')
    for sheet in workbook.sheets():
        if sheet.name == "Sheet_name_from_xlsm_file":
            with open('{}.csv'.format(sheet.name), 'wb') as f:
                writer = csv.writer(f)
                for row in range(sheet.nrows):
                    out = []
                    for cell in sheet.row_values(row):
                        try:
                            out.append(cell.encode('utf8'))
                        except:
                            out.append(cell)
                    writer.writerow(out)
