I have an Excel file (.xlsx) with 0.5 million rows that I want to read row by
row (using [this Nimble package](https://github.com/ringabout/xlsx) and then
looping through the rows using a `for` loop) and transform some of the values
(e.g. split full names into first name, middle name, last name, check some
values against `case` statements etc.) and insert them into a remote Postgres
database (actually I have multiple tables to insert into).

Do you think Nim is upto the job? I only have 8GB of RAM in my system.
