Read Excel file via pandas

While using pandas to read the header @ Line 15, parse.py, would it take a long time given a lot of empties columns in the Excel template?

so far when running the Excel Uploader with the Example CRIPT Excel Template, I have not encountered any significant performance issues.

I think your comment makes sense, but so far I've found that reading the Excel file with Pandas has been pretty quick for most cases.

If we want to optimize performance, maybe we could convert the Excel file into CSV, and use Pandas read_csv function instead to avoid empty columns.

However, for now I have not seen any crazy performance issues, and I think the user would not mind waiting 3 minutes for their data to upload. If it becomes an issue then we can tackle it then and start optimizing.
