To convert from numbers to letters, call the _column_letter() function. To convert from letters to numbers, call the _index_from_string() function. Note that the max_column method returns an integer rather than the letter that appears in Excel.Ĭonverting Between Column Letters and Numbers Enter the following into the interactive shell: You can determine the size of the sheet with the Worksheet object’s max_row and max_column member variables. Note that the integer 2, not the string 'B', is passed. The for loop’s i variable is passed for the row keyword argument to the cell() method, while 2 is always passed for the column keyword argument. By passing 2 for the range() function’s “step” parameter, you can get cells from every second row (in this case, all the odd-numbered rows). Say you want to go down column B and print the value in every cell with an odd row number.

Then, using the cell() method and its keyword arguments, you can write a for loop to print the values of a series of cells. > for i in range(1, 8, 2): print(i, sheet.cell(row=i, column=2).value)Īs you can see, using the sheet’s cell() method and passing it row=1 and column=2 gets you a Cell object for cell B1, just like specifying sheet did.
Continue the interactive shell example by entering the following: The first row or column integer is 1, not 0. As an alternative, you can also get a cell using the sheet’s cell() method and passing integers for its row and column keyword arguments. Specifying a column by letter can be tricky to program, especially because after column Z, the columns start by using two letters: AA, AB, AC, and so on. The datetime data type is explained further in Chapter 16. OpenPyXL will automatically interpret the dates in column A and return them as datetime values rather than strings.
The row attribute gives us the integer 1, the column attribute gives us 'B', and the coordinate attribute gives us 'B1'. Here, accessing the value attribute of our Cell object for cell B1 gives us the string 'Apples'. Cell objects also have row, column, and coordinate attributes that provide location information for the cell. The Cell object has a value attribute that contains, unsurprisingly, the value stored in that cell. > 'Cell ' + c.coordinate + ' is ' + c.value > 'Row ' + str(c.row) + ', Column ' + c.column + ' is ' + c.value > wb = openpyxl.load_workbook('example.xlsx') Once you have a Worksheet object, you can access a Cell object by its name.

These are exactly the sort of boring, mindless spreadsheet tasks that Python can do for you.Īlthough Excel is proprietary software from Microsoft, there are free alternatives that run on Windows, OS X, and Linux. Or you might have to look through hundreds of spreadsheets of department budgets, searching for any that are in the red. Or you might have to go through thousands of rows and pick out just a handful of them to make small edits based on some criteria. For example, you might have the boring task of copying certain data from one spreadsheet and pasting it into another one. The openpyxl module allows your Python programs to read and modify Excel spreadsheet files. Excel is a popular and powerful spreadsheet application for Windows.
