Excel DocumentsAn Excel spreadsheet document is called a workbook which is saved in a file with .xlsx extension. The first row of the spreadsheet is mainly reserved for the header, while the first column identifies the sampling unit. Each workbook can contain multiple sheets that are also called a worksheets. A box at a particular column and row is called a cell, and each cell can include a number or text value. The grid of cells with data forms a sheet. The active sheet is defined as a sheet in which the user is currently viewing or last viewed before closing Excel. Reading from an Excel fileFirst, you need to write a command to install the xlrd module. pip install xlrd Creating a WorkbookA workbook contains all the data in the excel file. You can create a new workbook from scratch, or you can easily create a workbook from the excel file that already exists. Input File We have taken the snapshot of the workbook. Code # Import the xlrd module import xlrd # Define the location of the file loc = ("path of file") # To open the Workbook wb = xlrd.open_workbook(loc) sheet = wb.sheet_by_index(0) # For row 0 and column 0 sheet.cell_value(0, 0) Explanation: In the above example, firstly, we have imported the xlrd module and defined the location of the file. Then we have opened the workbook from the excel file that already exists. Reading from the PandasPandas is defined as an open-source library which is built on the top of the NumPy library.

We can also read data from the existing spreadsheet using openpyxl. It also allows the user to perform calculations and add content that was not part of the original dataset. Example import openpyxl my_wb = openpyxl.Workbook() my_sheet = my_wb.active my_sheet_title = my_sheet.title print("My sheet title: " + my_sheet_title) Output: My sheet title: Sheet To learn more about openpyxl, visit our complete tutorial Click Here.
