it depends how the .txt file is arranged at the moment. you should paste up an example here.
you need to make it so each 'field' in the database has an entry in the text file. which means you might have to introduce some blanks, if they are missing.
if all the data in the text file is already seperated out with commas, or semi-colons, or whatever, then it could be as simple as just renaming the file type extension to .csv
