This first step editing the file extension is absolutely pointless, a CSV is just a text file so you can open it and edit it directly with any text editor. It is not solution. We can not open with notepad! Show 1 more comment. Querying is setup like how you filter a table in Excel Better yet, if one is open to installing the Power Query add-in, it's super simple and quick.

Advise me please if I Am wrong here. You are definitely doing something wrong such as storing large chunks of data in memory, or using convenience features such as getting lists of rows that inherently store everything in memory but are only suitable for small datasets.
