A solution that improves work with Google data sheets and extends their functionality.

Works as an add-on to Google Sheet.

The intuitive interface makes it easy to write complex formulas in the Spreadsheet without the necessary knowledge.
You can download external data, import from the outside from any website to the Spreadsheet, e.g. financial data, exchange rates, stock prices, etc.
It also has data cleaning functions, such as removing duplicate lines / lines, spaces, punctuation, case conversion, number rounding e.t.c.

It is available in a free version, but with great limitations.
Here, for a one-time fee, the solution is for a lifetime offer.

I recommend.
