Permanently Disable Scientific Notation in Excel

Anonymous

When you open a CSV file, just by double clicking on it, it automagically converts your usable data into unusable trash.

99.99999% of the people using Excel are business users. They are not "scientists". And business users have ZERO application for "scientific notation".

According to the text, this seems to only work when pasting data into Excel. Not when you are delivered a CSV file via a report or some 3rd party system/user. There are a bazillion apps that export tables of data to a CSV file. And the natural inclination of the business user is to simply double click on the CSV to view the file, which opens Excel. And then Excel does the dumbest thing imaginable with numbers larger than 15 chars. It converts it to "scientific notation".

Here's a thought. I know this will sound crazy. BUT DO NOT DO ANYTHING WITH MY DATA. JUST LEAVE IT BE.

And yes, I know how to use the Text/CSV import and transform my data. But that is me. My business users do not know how to do this. Nor do they want to go through the hassle of the extra clicks just to open a CVS file without Excel corrupting their data.

Principle of Least Astonishment - Don't do dumb things. Do nothing instead.

And as a software developer/product manager, if my software was corrupting user data, that is a severity 1 bug that needs fixed ASAP.

JUST STOP CORRUPTING MY DATA.

    The scientific notation is a very frustrating aspects of Excel. It is disappointing the Microsoft agents simply ask you to provide feedback. Thanks for making this post.
