Create Excel-Sheet without Excel (Excel 97-Format)

VB6-Sourcecode to generate Excel-Sheets without real using Excel. The Excel-Sheet must (byte-per-byte) created by native Basic coding. Format to be generated must be (minimum) Excel97-Format, especially multisheet-support must be implemented. Lower Format are not accepted. What i want is a solution to generate Excel Files with multiple sheets, with several cells, formats, formulas and the other things Excel can do. (Graphs were great, but no must) The solution must NOT use any dll-files. I must have all the source! More facts: The solution will be integrated in of my applications, so it should be some "save-as-excel"-functionality. For example I need a sub for 1. add a cell to sheet 2. add a formula 3. name a range 4. Make formatting (font, colors...) (5. create graph?) Sorry, but me english is not the best, hope not to confuse you.... ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
