Personal project as proof of competence

I am creating a file (Excel/GoogleSheet) allowing real-time monitoring of a stock/ETF portfolio according to the transactions carried out, graphs and tables updating automatically, etc.

Being interested in data analysis, and not currently working in this sector at all,
I was wondering if carrying out a personal project such as this is a good choice to present during a job interview, if I wish to change professional path

analysis data data analysis datascience etc etf excel file good graphs monitoring portfolio project real-time sector stock tables transactions
