parseToMaps static method

List<Map<String, dynamic>> parseToMaps(String content, { List<TCsvColumn>? columns, String? delimiter, })

Parses any supported format (CSV, TSV, DSV, JSON) directly into typed Maps. If columns schema is provided, applies auto-mapping and type coercion.

Implementation

static List<Map<String, dynamic>> parseToMaps(
  String content, {
  List<TCsvColumn>? columns,
  String? delimiter,
}) {
  final result = parseGeneric(content, delimiter: delimiter);
  if (result.isEmpty) return [];

  if (columns != null && columns.isNotEmpty) {
    final mapping = TCsvHeaderMapping.autoMap(
      expectedColumns: columns,
      csvHeaders: result.headers,
    );

    return result.rows.map((row) {
      return mapping.mapRow(
        expectedColumns: columns,
        csvHeaders: result.headers,
        csvRow: row,
      );
    }).toList();
  }

  // No columns schema provided: return direct map from headers to row values
  if (result.jsonMaps != null) {
    return result.jsonMaps!;
  }

  return result.rows.map((row) {
    final map = <String, dynamic>{};
    for (int i = 0; i < result.headers.length; i++) {
      final header = result.headers[i];
      map[header] = i < row.length ? row[i] : null;
    }
    return map;
  }).toList();
}
