What is the difference between browser mode and server mode in this CSV formatter?
Browser mode formats CSV in the current tab with csv-parse/sync and Papa Parse. Server mode sends the CSV to the hosted formatter path that uses csvformat from csvkit. Choose Browser mode when you want local browser processing, and Server mode when you specifically want the hosted server execution path.
