Key Terminology & Definitions
RFC 4180 Quoting Rule
If fields are not enclosed with double quotes, then double quotes may not appear inside the field. If double-quotes are used to enclose fields, a double-quote in a field must be escaped by preceding it with another double quote (`""`).
Tab-Delimited Clipboard
When selecting and copying a grid of cells in Excel or Google Sheets, the operating system clipboard stores the data as tab-separated plaintext.
