I think this is a very relevant topic to discuss, as lots of traditional heavy Excel users are learning Python and migrating their existent Excel sheets into Python code.
I understand this question as broader, then Eikon Data APIs or even Refinitiv APIs.
From what I see online, I think you may find to be a useful read:
And following up on this read, designing the custom app's structure, identifying required inputs, outputs, calculations.
Next, to integrate Eikon content via Python and Eikon Data APIs, I would go through
Is this helpful?
Many thanks, this is helpful. Eikon Data API resources and tutorials were known to me already and this 'towardsdatascience' article is interesting, however not relevant to Eikon.
So there are no exact Refinitiv guides like:
"Here is Eikon Excel formula and here is Eikon Python formula to compare for main cases?"
No, I am afraid there is no short-circuit way to migrate a spreadsheet, one has to go line by line and examine the content.
The code will, most of the time, look very similar to formula, for instance see this discussion for an example.
In many cases we use RSerach to identify the correct python parameters such as this question.
The other very used tool is Data Item Browser or DIB, you may find this article to be relevant on DIB usage.
