Try the xlrd library    Edit  - from what I can see from your comment  something like the snippet below might do the trick  I m assuming here that you re just searching one column for the word  john   but you could add more or make this into a more generic function   from xlrd import open workbook  book   open workbook  simple xls  on demand True  for name in book sheet names        if name endswith  2            sheet   book sheet by name name             Attempt to find a matching row  search the first column for  john           rowIndex   -1         for cell in sheet col 0                  if  john  in cell value                  break            If we found the row  print it         if row    -1              cells   sheet row row              for cell in cells                  print cell value          book unload sheet name

Edit   In the newer version of pandas  you can pass the sheet name as a parameter    file name      path to file   file name sheet      sheet name or sheet number or list of sheet numbers and names  import pandas as pd df   pd read excel io file name  sheet name sheet  print df head 5      print first 5 rows of the dataframe   Check the docs for examples on how to pass sheet name  https   pandas pydata org pandas-docs stable generated pandas read excel html  Old version   you can use pandas package as well      When you are working with an excel file with multiple sheets  you can use   import pandas as pd xl   pd ExcelFile path   filename  xl sheet names   gt  gt  gt   u Sheet1   u Sheet2   u Sheet3    df   xl parse  Sheet1   df head     df head   will print first 5 rows of your Excel file  If you re working with an Excel file with a single sheet  you can simply use   import pandas as pd df   pd read excel path   filename  print df head

This isn t as straightforward as opening a plain text file and will require some sort of external module since nothing is built-in to do this  Here are some options    http   www python-excel org   If possible  you may want to consider exporting the excel spreadsheet as a CSV file and then using the built-in python csv module to read it   http   docs python org library csv html
