//catch error
do {
	let csv = try CSVParser(filePath: "path/to/csvfile")
}catch {
	// Error handing
}

do {
	let csv = try CSVParser(filePath: "path/to/csvfile", delimiter: ";")
}catch {
	// Error handing
}

// init from elements
let csv = try CSVParser(elements: [["a", "b", "c"], ["1", "2", "3"]])

Read data

do {
	let csv = try CSVParser(filePath: "path/to/csvfile")
	// get every row in csv
	for row in csv {
        print(row) // ["first column", "sceond column", "third column"]
    }
    
    // get row by int subscript 
    csv[10] // the No.10 row
    
    // get column by string subscript
    csv["id"] // column with header key "id" 
	
}catch {
	// Error handing
}

Write data

do {
	let csv = try CSVParser(filePath: "path/to/csvfile")
	// get every row in csv
	csv[0] = ["test0", "test1", "test2"]
	csv.wirite(toFilePath: "path/to/destination/file")
	
}catch {
	// Error handing
}

Subscript

// get row by int subscript 
csv[10] // the No.10 row
    
// get column by string subscript
csv["id"] // column with header key "id" 

Get dictionary elements

for dic in csv.enumeratedWithDic() {
	print(dic) // dic is [String: String]	
}

CSV to JSON

The result json type is [{"header0": "a","header1": "b"},{"header0": "a", "header1": "b"}]

do {
	let jsonStr = try csv.toJSON()
}catch {
	// Error handing
} 

JSON to CSV string

Now only support this json type [{"header0": "a","header1": "b"},{"header0": "a", "header1": "b"}]

do {
	let csvString = try CSVParser.jsonToCSVString(jsonData: jsonData) // jsonData is the Data type ot json
}catch {
	// Error handing
}
