function locateJsonError(rawJson) {
  try {
    JSON.parse(rawJson);
    return { valid: true };
  } catch (err) {
    const match = err.message.match(/position\s+(\d+)/i);
    if (match) {
      const pos = parseInt(match[1], 10);
      const lines = rawJson.substring(0, pos).split('\n');
      return {
        valid: false,
        line: lines.length,
        column: lines[lines.length - 1].length + 1,
        message: err.message
      };
    }
    return { valid: false, message: err.message };
  }
