Encode a CSV as Base64
CSV is the world's most pragmatic data interchange format. Base64-encoding it turns a delimited file into an opaque ASCII payload that survives JSON fields, email bodies, signed URLs, and any other channel that prefers text over multipart uploads. Pick a Data URI if you want a one-click download link, JSON if you need a structured wrapper for an API call.
