Change large table into panel data format

Can you upload a worksheet with sample data? Or better yet, the real data?

Your post does not comply with Rule 1 of our Forum RULES. Your post title should accurately and concisely describe your problem, not your anticipated solution. Use terms appropriate to a Google search. Poor thread titles, like Please Help, Urgent, Need Help, Formula Problem, Code Problem, and Need Advice will be addressed according to the OP's experience in the forum: If you have less than 10 posts, expect (and respond to) a request to change your thread title. If you have 10 or more posts, expect your post to be locked, so you can start a new thread with an appropriate title.
To change a Title on your post, click EDIT then Go Advanced and change your title, if 2 days have passed ask a moderator to do it for you.

Hi stevenm, thanx for your reply so soon. The data is confidential, but I have here a sample excel spreadsheet. If it works on this sheet, it will work on mine.

Slightly complicated...

I think you should rearange your data to use it with Pivot table...

But here:

You're awesome, I tried a pivot, but didn't get the desired result properly. I'm gonna try it now

Hi

I would like to ask if the suggested idea worked out for you? If not, then how did you solve the problem?

I have similar problem, I have a data set of 535 companies, with daily stock returns for 20 years.

Kind regards

It worked. You'll have to combine it with the 'transpose function' and 'pivot table' function in excel. In that way you can turn your table around as much as you like. Use zbor's code and you'll be fine! Btw, zbor: thanx a lot for your help!

Hello Zaub, and welcome to the forum.

Unfortunately you have inadvertently broken one of the forum rules. Please read the following and make the necessary change. Thanks.

Your post does not comply with Rule 2 of our Forum RULES. Don't post a question in the thread of another member -- start your own thread. If you feel it's particularly relevant, provide a link to the other thread. It makes sense to have a new thread for your question because a thread with numerous replies can be off putting & difficult to pick out relevant replies.

An excellent way to do the conversion is to use the inbuilt features of Stata as suggested by Angel here http://angelsmarrero.blogspot.ca/201...-in-stata.html
