    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 = require('detect-csv')
     
    var csv = detect('a,b,c\n1,2,3')
     
    console.log(csv.delimiter)
    console.log(csv.newline)
    // prints ',' and '\n'
     
    var isCsv = detect('notacsv')
    console.log('This is ' + (isCsv ? '' : 'not') + ' a csv') 
    // 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. \r\n.

    Install
