About Data tools
How big a file can I paste?
A few megabytes of text is comfortable. Beyond that the browser slows down; that is a limit of pasting rather than of the conversion itself.
Does the CSV parser handle quoted commas?
Yes — quoted fields, escaped double quotes inside them, and empty trailing cells all parse correctly. Line breaks inside quoted fields are the one case still on the list.
