wb = openpyxl.load_workbook(filename)
ws = wb.get_sheet_by_name('Sheet1') # gets Sheet1 in excel
rowcount=ws.max_row

def say(s):
    voice = tts.sapi.Sapi()
    voice.set_voice("Zira")#u can use the voice of David also
    #you set the rate to say slowly as shown below
    #voice.set_rate(-5)
    filename=str(ws.cell(row=i+1,column=1).value)+'.wav'
    voice.create_recording(filename, s)




if __name__== "__main__":

       for i in range(rowcount):              # loop through entire rows in excel

               mytext = str(ws.cell(row=i+1,column=1).value) # gets the first column data
