Code
add_filter( 'upload_mimes', function ( $mimes ) {
if ( ! current_user_can( 'manage_options' ) ) {
return $mimes;
}
// Extension => MIME type.
$types = array(
'json' => 'application/json',
'csv' => 'text/csv',
'xml' => 'application/xml',
'md' => 'text/markdown',
);
return array_merge( $mimes, $types );
} );
add_filter( 'wp_check_filetype_and_ext', function ( $data, $file, $filename, $mimes ) {
if ( ! empty( $data['ext'] ) || ! current_user_can( 'manage_options' ) ) {
return $data;
}
$check = wp_check_filetype( $filename, $mimes );
if ( in_array( $check['ext'], array( 'json', 'csv', 'xml', 'md' ), true ) ) {
$data['ext'] = $check['ext'];
$data['type'] = $check['type'];
}
return $data;

Only users with the manage_options capability get the extra file types. Edit $types to add or remove extensions.
