❓ FAQ
What is formula escape?
If a cell starts with = + - @, Excel treats it as a formula (CSV injection risk). We prefix a single quote so it is treated as text.
Should I use LF or CRLF?
CRLF for Windows Excel. LF works fine in Mac/Linux editors and Google Sheets.
Can a cell contain a line break?
Yes. With RFC 4180 quotes ON, double-quoted fields keep internal line breaks.
