Hi Karl, Thank you for your reply. Yes, I've tested your sample and also downloaded the files(txt file and pdf file), it works. The form is below. Just as the code I put above, what I need to do is only to fill one field, not all(e.g. Title field). So do I also need to fill every field on this page and export the data? Another question is: You said that "You need exactly the same number of columns with data in you text file as you have fields in your document." But in my case, this form is a little bit different from your sample form because the columns are not regular and atactic. So I don't know how to calculate the number of the columns. In your sample, the data is : one column has many data(fields), e.g. many email addresses under "email column", my case is each fillable blank only need to be filled with one field, e.g. only "Mr." is under "Title".
