Dear Statalist Users,

as a beginner, I am having some trouble importing large excel datatables containing datastream output into stata long format. I checked with faq/help files and think that the reshape command combined with some data manipulations must be the answer. Right now I can get the data to look like this in Stata: |v1|v2|v3|v4|v5|... |.|ID code1|ID code2|ID code3|ID code4|... |date1| Xij|Xij|Xij|Xij|...
|date2| Xij|Xij|Xij|Xij|...
|...|...|...|...|...

where Xij = Data

However from my past Stata experiences the usual long form is much better to work with:

|ID code1|date1|Xij|
|ID code1|date2|Xij|
|...|...|...|
|ID code2|date1|Xij|
|ID code2|date2|Xij|
|...|...|...|

I think reshape will solve this for me, but I couldn't get anything to work...
Please offer advice, thank you.

Si Yue
