It would not be wise to say that Excel and Google Sheets are the same programs. They are for similar jobs, but Microsoft Excel is now a very powerful tool for working with data. Powerful add-ons (Power Pivot, Power Query, Power BI, etc.) increase the volume of work with data to unprecedented proportions.
There is almost no person in the business world who, in addition to the fancy Apple iPhone, does not have an Android phone if the “smartphone” is a phone at all.
Where is the difference?
Both programs are designed to work with data and overlap in large part, which actually means that you can do many jobs in one program and download it to another program to complete the work, perhaps with functions that are not in the first program. It can be UNIQE, FILTER, GOOGLETRANSLATE, etc. I will deal with the use of Google spreadsheets in the following posts.
Now I will only list what is almost identical for both programs: working with formulas, diagrams, pivot tables, conditional formatting, macro commands, filters, slicers, etc.
For most users it is more than enough.
