I will try to add more support for other data formats like xlsx and parquet in the future. Current CSV parsing is also a bit limited (i.e. cannot deal with timestamps) so I will try to update parsers first. Also thanks for the error checker! I pushed the fixes in https://github.com/visprex/visprex.github.io/pull/4 https://github.com/visprex/visprex.github.io/pull/4
