After searching a bit about the method to open the existing sheet in xlxs, i discovered

existingWorksheet = wb.get_worksheet_by_name('Your Worksheet name goes here...')
existingWorksheet.write_row(0,0,'xyz')

You can now append/write any data to the open worksheet. I hope it helps. Thanks

You cannot append to an existing xlsx file with xlsxwriter   There is a module called openpyxl which allows you to read and write to preexisting excel file  but I am sure that the method to do so involves reading from the excel file  storing all the information somehow  database or arrays   and then rewriting when you call workbook close   which will then write all of the information to your xlsx file   Similarly  you can use a method of your own to  append  to xlsx documents  I recently had to append to a xlsx file because I had a lot of different tests in which I had GPS data coming in to a main worksheet  and then I had to append a new sheet each time a test started as well  The only way I could get around this without openpyxl was to read the excel file with xlrd and then run through the rows and columns     i e   cells      for row in range sheet nrows       cells append         for col in range sheet ncols           cells row  append workbook cell row  col  value    You don t need arrays  though  For example  this works perfectly fine   import xlrd import xlsxwriter  from os path import expanduser home   expanduser         this writes test data to an excel file wb   xlsxwriter Workbook     Desktop test xlsx  format home   sheet1   wb add worksheet   for row in range 10       for col in range 20           sheet1 write row  col   test           format row  col   wb close      open the file for reading wbRD   xlrd open workbook     Desktop test xlsx  format home   sheets   wbRD sheets      open the same file for writing  just don t write yet  wb   xlsxwriter Workbook     Desktop test xlsx  format home      run through the sheets and store sheets in workbook   this still doesn t write to the file yet for sheet in sheets    write data from old file     newSheet   wb add worksheet sheet name      for row in range sheet nrows           for col in range sheet ncols               newSheet write row  col  sheet cell row  col  value   for row in range 10  20     write NEW data     for col in range 20           newSheet write row  col   test           format row  col   wb close     THIS writes   However  I found that it was easier to read the data and store into a 2-dimensional array because I was manipulating the data and was receiving input over and over again and did not want to write to the excel file until it the test was over  which you could just as easily do with xlsxwriter since that is probably what they do anyway until you call  close
