Detect if a chunk in the beginning of a CSV (in the sense of character seperated values)
is valid and determine the delimiter character. Install with
npm install detect-csv
Right now it only parses the first line and counts characters. So the rest of the CSV might be invalid. Also I recommend checking for json/ndjson first, since it's the more strict format.
var detect =var csv =consoleconsole// prints ',' and '\n'var isCsv =console// prints: This is not a csv
You add the following options as a second parameter:
- delimiters Delimiters to detect, defaults to
[',', ';', '\t', '|']
- newlines Newline characters to detect, defaults to ['\n', '\r']
Delimiters and newlines don't work with multiple characters, e.g.
