Use Base64 wisely
Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Frequently asked questions
When should I use Base64 for Base64 CSV data?
Use it when a text-only channel or API must carry binary data, or when a small payload involving Base64 CSV data needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
