Turns out AppCues CSV files can be big, and cause Numbers1 to have a panic attack. Using the magic of Node Streams, we can process the file line-by-line for reduced RAM use/user sadness.
- Install the deps using your favourite package manager
- Run the program with
./index.js --infile=appcues-export.csv --outfile=stuffyouwant.txt [--maxlen N]
The maxlen argument is optional, and allows output to be split over mutiple files,
e.g. for if you want to run a database query (technically the outfile arg is also optional, but your filtered data gets sent to a no-op stream. Poor data.)
1Or other spreadsheet program of your choice, I guess.
