}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"}]

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