The specific problem is that after importing, the data fits into STATA without any problem (it doesn't exceed the 244 charterers restriction). The problem is that everything is compressed in the same cell without any spaces to split for. Example: AgeatFinancingMonths1 116 73 69 57 41 34 17 14 0 In STATA dta type stays like this... AgeatFinancingMonths1 116736957413417140 ( tel:116736957413417140) There is no regular pattern to count the months or the continuous variables. I tried pasting the excel data first in a text editor (actually, pasting the data in the Eviews command window) first and then copy it from that editor and finally paste it into STATA editor. It worked but doing it column by column.. Could you guys have any thoughts to do this with a text editor or something? They preserve the formats... >>> Eric Booth <eric.a.booth@gmail.com> 2012-04-12 15:49 >>> <> No. There isn't any part of -import excel- that tells Stata to split those cells while importing. However, the second response in my last message does tell you some strategies & warning about how to split those cells after importing (or that you can try to pre-process the file). You have to tell Stata _how_ to split those cells/variables and that may vary variable by variable. If you have a specific question about how to split those cells after importing or how to pre-process the file let us know. - Eric __ Eric A.

However, where you have other delimiters in a cell/string, you'd need to adjust -split-'s parse() option (or some other string_function) accordingly. Finally, if you have different numbers of elements within a string, you'll get different numbers of variables created by -split-, so you'll have to do some work to organize your new variables, but without seeing that data I couldn't guess about the strategy. > > - Eric > > > > __ > Eric A.
