  • arrData is an array containing array of strings
  • skipVoid if true skip void lines, if not present is set to false

    // first line is header
    var headers = ppData[0];
    // remove first line
    ppData.splice(0, 1);
    // convert in array of objects
    var arraOfObjects = Banana.Converter.arrayToObject(fileData.headers, ppData, true);

csvToArray(string [, separator, textdelim])

Convert a csv file (coma separated values) to an array of array.

The parameter string contains the text to convert. The parameter separator specify the character that separates the values, default is a comma ','. The parameter textDelim specify the delimiter character for text values, default is a double quote '"'.

var table = Banana.Converter.csvToTable(text);
var value = table[0][1];
value == '2'; // true

flvToArray(string, fieldLengths)

Convert a flv file (fixed length values) to an array of array.

The parameter string contains the text to convert. The parameter fieldLengths is an array with the lengths of the fields.

Example:

//               6                  20       8
var text = "120608Phone               00002345";
var table = Banana.Converter.flvToTable(text, [6,20,8]);
