For file payloads, use Image to Base64 or recover an inline asset with Base64 to Image.
Encode a CSV table into Base64 to stash it inside a single transportable string — convenient for emailing fixtures, attaching to bug reports, or stuffing rows inline in JSON.
RFC 4180 quoting and any custom delimiters are preserved byte-for-byte. The encoder makes no attempt to detect or modify the delimiter.
Yes — Base64 simply encodes the bytes, so RFC 4180 quoting and embedded commas survive untouched.
No. Whatever bytes are in your input are encoded verbatim; delimiter detection is the consumer's responsibility.
If the file starts with a BOM, the BOM is included in the encoded output. Strip it externally if needed.
No. All encoding runs locally in your tab.
