The clear lesson of this whole débacle:
Everyone still using Excel needs to learn to use R.
Not saying throw out Excel — keep using it for data entry or anything non-quant-facing — but please bring in R or Python for the important stuff 🤓🙏
Start here: https://www.tidyverse.org/learn/
And to be clear, when I say "by all means keep using Excel for data entry" I don’t mean manually entering or combining more than 1 million rows of data. That is just ... wild.
The very idea of handling huge files like that brings me out in a cold sweat 😅😅
To be fair I should also note that if — like me — you are a reckless and impatient coder, you can still trip up with R...
