toJsonFromRows static method

String toJsonFromRows(List<String> headers, List<List> rows, { bool pretty = true, List<TCsvColumn>? columns, })

Converts headers and rows to a formatted JSON string.

Implementation

static String toJsonFromRows(
  List<String> headers,
  List<List<dynamic>> rows, {
  bool pretty = true,
  List<TCsvColumn>? columns,
}) {
  final maps = rows.map((row) {
    final map = <String, dynamic>{};
    for (int i = 0; i < headers.length; i++) {
      final header = headers[i];
      final val = i < row.length ? row[i] : null;

      if (columns != null) {
        final col = columns.firstWhere(
          (c) => c.header == header || c.key == header,
          orElse: () => TCsvColumn.text(key: header, header: header),
        );
        map[col.key] = col.parseValue(val);
      } else {
        map[header] = val;
      }
    }
    return map;
  }).toList();

  return toJson(maps, pretty: pretty);
