It will be numeric data, real numbers. >What is the file format? Wiley Press (605 Third Avenue, NY, NY 10158) publishes several books on file formats for PC software by author Jeff Walden. I have the 1986 printing of "File Formats for Popular PC Software" that includes 1-2-3 1.x and 2.0. I would expect that a more recent version would cover 2.2 and higher. Lotus uses a complex format that is not easily explained. The above book, or one like it, will be your best reference.
