Converting a csv file to json using C#

Question

I was wondering if someone\'s written a utility to convert a CSV file to Json using C#. From a previous question on stackoverflow, I\'m aware of this nice utility - https://

Answer 1

Here's mine.. It can parse 9k CSV records in centuries. LOL

class CSVTOJSON
{
    public string ConvertToJSON()
    {
        string json = string.Empty;
        string csv = string.Empty;

        using (StreamReader reader = new StreamReader("data.csv"))
        {
            csv = reader.ReadToEnd();
        }

        string[] lines = csv.Split(new string[] { "\n" }, System.StringSplitOptions.None);

        if (lines.Length > 1)
        {
            // parse headers
            string[] headers = lines[0].Split(',');

            StringBuilder sbjson = new StringBuilder();
            sbjson.Clear();
            sbjson.Append("[");

            // parse data
            for (int i = 1; i < lines.Length; i++)
            {
                if (string.IsNullOrWhiteSpace(lines[i])) continue;
                if (string.IsNullOrEmpty(lines[i])) continue;

                sbjson.Append("{");

                string[] data = lines[i].Split(',');

                for (int h = 0; h < headers.Length; h++)
                {
                    sbjson.Append(
                        $"\"{headers[h]}\": \"{data[h]}\"" + (h < headers.Length - 1 ? "," : null)
                    );
                }

                sbjson.Append("}" + (i < lines.Length - 1 ? "," : null));
            }

            sbjson.Append("]");

            json = sbjson.ToString();
        }

        return json;
    }
}

But it works.
