You don't need an entire table, just one cell. Determine total number of rows . To directly format cells using openpyxl version 3 (v3.0.9), the following code was required: from openpyxl import Workbook wb = Workbook() ws = wb.create_sheet(title='testSheet') _cell = ws['A1'] _cell.number_format = '0.00E+00' The cell can be formatted directly as follows: ws['A1'].number_format = '0.00E+00' In column_dimensions, one can access one of the objects using the letter of the column (in this case, A or B). The openpyxl module allows Python program to read and modify Excel files. Edit: In the newer version of pandas, you can pass the sheet name as a parameter. You can do that by specifying the cell you want to change and then setting it to a new value. startup_select selects cells, rows or columns at initialization by using a tuple e.g. NB.

When you run this code, you should see the following output: Determine total number of rows . max_row-This gives the maximum row index containing data (1-based) Prerequisite: Reading & Writing to excel sheet using openpyxl Openpyxl is a Python library using which one can perform multiple operations on excel files like reading, writing, arithmetic operations and plotting graphs.Lets see how to perform different arithmetic operations using openpyxl. The way I do it is to make that cell a header, for example: # Read Excel and select a single cell (and make it a header for a column) data = pd.read_excel(filename, 'Sheet2', index_col=None, usecols = "C", header = 10, nrows=0) We need to first fetch the number of rows and number of columns in the sheet.
