I sometimes run into issues when setting up a local repo because of the new main default branch name on GitHub. Let's rename the local branch and set its upstream properly.

git branch -m master main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a

NOTE: git remote set-head origin -a fetches and sets origin/HEAD, so that the local repository has a local reference of what the remote repository considers to be the default branch.

StringBuilder jsonData = new StringBuilder();
jsonData.Append("[");
for (int i = 0; i < dt.Rows.Count; ++i)
{
    jsonData.Append("{");
    jsonData.Append("\"" + "DNI" + "\":" + "\"" + dt.Rows[i][0] + "\"" + "," + "\"" + "Name" + "\":" + "\"" + dt.Rows[i][1] + "\"" + ",");
    jsonData.Append("\"" + "Telephone" + "\":" + "\"" + dt.Rows[i][2] + "\"" + "," + "\"" + "Observations" + "\":" + "\"" + dt.Rows[i][3] + "\"");

    if (i == dt.Rows.Count - 1) { jsonData.Append("}"); }
    else { jsonData.Append("},"); }
