I have tried that and still gives the same Permission denied error.

If its opened in Excel as read-only, python can open the file for write, and edit it.

Problem is, that Excel can only refresh cell data without closing and reopening a file if it comes from an external connection (at least according to this ).

So while it worked with an imported csv, Im not sure it would work here.

The following code opens an existing Excel file called Example.xlsx and updates it in real time, in this case puts in the value 45 in cell B2 instantly soon as you run the script.

Other tools, e.g.

They extract the xlsx file, which is a zip file, and import the data into an empty spreadsheet.

You cant write to it directly, but you can use win32com to communicate with the copy of Excel that is running via its COM interface.

The objects you get back arent Python objects but a thin Python wrapper around VBA objects that obey their own conventions, not Pythons.

So the Excel objects you get back from it are no harder or easier to use because the behaviour is identical.

Anyhow, you have a working solution and that is why you posted on SO.

If youve ever used the Bloomberg add-in use for accessing real time market data in Excel then youll be familiar with RTD functions.

The pywin32 package includes an example that shows how to do that, however it only works for Excel prior to 2007.

For 2007 and later versions you will need this code to make that example work (see the modified example from pywin32 in exceltypesdemos in that repo).

Its the fact that the Excel program acquires a lock (at the operating system level) that prevents other applications from writing to the same file.

Some other application (such as the HxD hex editor) can happily open an Excel file without locking it.

Can a 2nd program open and write to a file that is already open in Excel on a Mac If so, again that is evidence against the file format having any bearing at all here (and indeed flatly contradicts your answer).

The specification mandates zip files as the package format and these are not editable inplace, this precludes concurrent editing.

But, hey, you know better so Im looking forward to your library.
