    xlrd xlrd is a library for reading data and formatting information from Excel files in the historical .xls format. Warning This library will no longer read anything other than .xls files. For alternatives that read newer file formats, please see . The following are also not supported but will safely and reliably be ignored: Charts, Macros, Pictures, any
    other embedded object, including embedded worksheets. VBA modules Formulas, but results of formula calculations are extracted. Comments Hyperlinks Autofilters, advanced filters, pivot tables, conditional formatting, data validation Password-protected files are not supported and cannot be read by this library. Quick start: import xlrd
    book = xlrd.open_workbook("myfile.xls") print("The number of worksheets is {0}".format(book.nsheets)) print("Worksheet name(s): {0}".format(book.sheet_names())) sh = book.sheet_by_index(0) print("{0} {1} {2}".format(sh.name, sh.nrows, sh.ncols)) print("Cell D30 is {0}".format(sh.cell_value(rowx=29, colx=3))) for rx in range(sh.nrows):
    print(sh.row(rx)) From the command line, this will show the first, second and last rows of each sheet in each file: python PYDIR/scripts/runxlrd.py 3rows *blah*.xls You may also wish to consult the tutorial. Details: For details of how to get involved in development of this package, and other meta-information, please see the sections below:

    Installation:- pip install xlrd Or you can use setup.py file from pypi Reading an excel sheet:- Import xlrd module and open excel file using open_workbook() method. import xlrd book=xlrd.open_workbook('sample.xlsx') Check number of sheets in the excel print book.nsheets Print the sheet names print book.sheet_names() Get the sheet
    based on index sheet=book.sheet_by_index(1) Read the contents of a cell cell = sheet.cell(row,col) #where row=row number and col=column number print cell.value #to print the cell contents Get number of rows and number of columns in an excel sheet num_rows=sheet.nrows num_col=sheet.ncols Get excel sheet by name sheets =

    files (.xls). In this tutorial, I will share with you how to use this library to read data from .xls file. Let’s get started with xlrd You will need to install this library with below pip command: and import the library to your source code: To open your excel file, you will need to pass in the full path of your file into the open_workbook function.It returns
    the workbook object, and in the next line you will be able to access the sheet in the opened workbook. workbook = xlrd.open_workbook(r"c:\test.xls") There are multiple ways for doing it, you can access by sheet name, sheet index, or loop through all the sheets sheet = workbook.sheet_by_name("Sheet") #getting the first sheet sheet_1 =
    workbook.sheet_by_index(0) for sh in workbook.sheets(): print(sh.name) To get the number of rows and columns in the sheet, you can access the following attributes. By default, all the rows are padded out with empty cells to make them same size, but in case you want to ignore the empty columns at the end, you may consider
    ragged_rows parameter when you call the open_workbook function. row_count = sheet.nrows col_count = sheet.ncols # use sheet.row_len() to get the effective column length when you set ragged_rows = True With number of rows and columns, you will be able to access the data of each of the cells for cur_row in range(0, row_count): for
    cur_col in range(0, col_count): cell = sheet.cell(cur_row, cur_col) print(cell.value, cell.ctype) Instead of accessing the data cell by cell, you can also access it by row or by column, e.g. assume your first row is the column header, you can get all the headers into a list as below: header = sheet.row_values(0, start_colx=0, end_colx=None) #
    row_slice returns the cell object(both data type and value) in case you also need to check the data type #row_1 = sheet.row_slice(1, start_colx=0, end_colx=None) Get the whole column values into a list: col_a = sheet.col_values(0, start_rowx=0, end_rowx=None) # col_slice returns the cell object of the specified range col_a =
    sheet.col_slice(0, start_rowx=0, end_rowx=None) There is a quite common error when handling the xls files, please check this article for fixing the CompDocError. Conclusion xlrd is a clean and easy to use library for handling xls files, but unfortunately there is no active maintenance for this library as Excel already evolved to xlsx format.
    There are other libraries such as openpyxl which can handle xlsx files very well for both data and cell formatting. I would suggest you to use xlsx file format in your new project whenever possible, so that more active libraries are supported. If you would like to understand more about openpyxl , please read my next article about this library.
    As per always, welcome to any comments or questions. Thanks.
