Issue title: Review doesn't say how to format datas already imported in a column
 Issue body: 
My point of view is that this article focus only on changing a cell format to display long numbers "correctly". Long numbers that will be written **later** in the cell.

The article does not answer the question : how to format a column into the right format for displaying correctly the long numbers into it ? Numbers that may have been imported from the import text tool. For example.

**This question is the one people have when reading the article.**

The answer to this question is : Format to specific numeric format, using numbers and with 0 (or more) decimals.

I think the doc should include this case if not answering specifically this case.

 Comment 0: @vcopleutre Thank you for the feedback. By default, excel can display up to 11 digits in a cell. Even in case you have a long number already in the cell the instructions to Format to a specific numeric format, using numbers and with 0 (or more) decimals. adds Zeros at the end. So the workaround is to delete the number, follow the steps in one of the methods and then type or import the long number again to the cell as mentioned in the document

Hope this helps!

Thanks
Sri
