<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />I have a folder with 500 files in txt format and want to import them JMP table, each txt file must correspond to a column in JMP. and each column must be added the name of the txt file...???
Thank you very much for the help
Very useful help, now I have the following problem.
Files in txt have two columns separated by a comma, what I want now is that every file is imported into a table of JMP and the two numbers are separated and placed each one in different columas, and assign the file name txt to the corresponding column.
I am attaching the txt file and as it should be in JMP table.
Thank you very much for the attention 

Could be automated with jsl in a number of ways. How to do it depends on the delimiter used and if the data columns are numeric, character or a mix of both.
This approach should work for numeric columns (although I can think of scenarios where it would fail):
dir = Pick Directory("Pick directory with .txt data files");
files = Files In Directory(dir);
// Remove non-.txt files from list
For(i = N Items(files), i > 0, i--,
If(Right(files[i], 4) != ".txt",
Remove From(files, i, 1)
)
);
delim = "\!n"; // Change this to current delimiter
n = N Items(files);
dt = New Table("500 files");
For(i = 1, i <= n, i++,
Pat Match(files[i], Pat Break(".") >> colname);
v = Words(Load Text File(dir || files[i]), delim);
dt << New Column(colname, values(v));
);
