If you really have to drive Excel on Mac, because you need to use existing files as templates, I suggest you look at Applescript. And sometimes it is just easier to visually setup a spreadsheet and then just fill the cells programmatically. I had to do so because I had no easy way to include Visual Basic macros and very specific formatting specified by a client.

If you have existing Excel files which you use as 'templates' with information that would get lost if you read/write using one of the above packages, then you have to go with updating the file in Excel. xlsx for writing (but xlrd can read those files).īoth are good enough for writing things like data, formula and basic formatting. You can of course overwrite the orginal file, so it looks like an update.įor 'updating' you can use the trio xlrd, xlwt, xlutils if the files you work with are. However updating is not the right word: you have to read in the file and write it out new. It is usually much easier, and certainly faster (wrt excution speed) to go with 'updating' an Excel file without starting Excel. Here's a sample (untested, because I don't have Excel here): import appscriptĮ.t('=A2+1')įrom the comments it is not completely clear if you need to 'update' an Excel file with data, and just assume that you need Excel to do so, or that you need to change some excel files to include new data. Despite the fact that it's been abandoned by its original creator, and is only being sparsely maintained, and will probably eventually stop working with some future OS X version, it's still much better than the official solutions. However, I'd probably use appscript (get the code from here). If you actually want to control Excel-e.g., open a document, make some changes, and save it-you'll want to use its AppleScript interface.Īpple's recommended way of doing that is via ScriptingBridge, or using a dual-language approach (write AppleScripts and execute them via NSAppleScript-which, in Python, you do through PyObjC).

Look at the NSWorkspace or open documentation to see how to do whatever you want. If you want to make Excel do something simple like open a specific document, that's not much harder.

Subprocess.check_call()Įither way, you're effectively launching Excel the same way as if the user double-clicked the app icon in Finder. If not, you can always use the open tool: import subprocess

If you have PyObjC (which you do if you're using the Python that Apple pre-installs on 10.6 and later otherwise, you may have to install it): import Foundation If all you need to do is launch Excel, the best way to do it is to use LaunchServices to do it.
