About the csv to json converter
CSV (comma-separated values) is the format spreadsheets export; JSON is what most web APIs and JavaScript code expect. Converting between them is one of the most common small data chores.
A naïve conversion breaks on quoted fields that themselves contain commas. This converter implements proper CSV parsing, so a value like “Smith, John” wrapped in quotes stays a single field, and doubled quotes inside a field are handled correctly.
Everything runs locally in your browser, which matters here: spreadsheets often contain customer records, pricing or other data you should not paste into an online service.
