Hello and welcome to Stata (nb not STATA)!

Firstly, make sure you have the latest version - there have been some updates since version 12 was released that have improved importing from Excel, including a problem where numeric cells were sometimes imported as strings. You can check for an update by running:
update query

If that doesn't help, to convert numbers in string format to numeric format, the command you're after is -destring- (use -help destring- to read about it, or you can access it via the menu Data -> Create or change data -> Other variable-transformation commands -> Convert variables from string to numeric)

The Stata documentation is very good; you could for example answer this question by typing:
search convert string

Also take a look at chapter 23 of the User's Guide, and of course all of the rest of the User's Guide too (!)

Some of the columns are imported as ¨strings¨which result in the numbers being red and I cant use them in the analysis. Does anyone know how to convert this format to the ordinary format or how to prevent that some of the data is imported as strings ??
