I have a really heavy excel file 400K rows, and I need, using cusip or ticker and date of shareholder meeting (variables for each row) to download data such as revenues, total asset, market cap, etc. for my thesis. I tried excel =TR(…) formula, but does not recognise cusip or ticker, while datastream recognise the ticker or u/ticker but when I run the formula for all rows my file stop to work, and excel crash. Therefore I tried using chatgpt trying to use python but it seems there is not a way to use datastream through python or at least I don’t have accademic API key. I have eikon and refinitiv API key. I tried using eikon but even through python can’t find the data, showing N/A or ticker not found, even if looking for the ticker within desktop app, the company can be found. If a value is found is different than the one downloaded in the few rows where datastream in excel worked. I don’t know how to populate my heavy database without crash.
Python provide several errors or no data (N/A)
What do you suggest?
First example
