Everything you enter or choose is processed by JavaScript in your browser and never sent anywhere. Only the page code, and any library this tool needs, is downloaded from cdnjs or jsDelivr.
Questions
Why add a BOM?
It helps Excel read accents and non-Latin letters correctly when you reopen the CSV.
Are formulas kept?
CSV stores values, so you get the calculated results and not the formulas.
