Excel xlsm file converted to a webpage

I have Excel Xlsm files that I want to be converted into a wedpage. The excel files are lesson tracker files for a company. I need people to add their lesson data to the files and then save them as they go. There is one workbook that I would like to act as a home page, this workbook then uses links to open other workbooks. The first workbook (homepage workbook) is 1.25MB. This workbook then has passworded links to access the other workbooks that are 10.28MB each (individual school workbooks). There would potentially be up to 20 (idividual school) 10.28MB workbooks. The workbooks contain macro's for printing, sorting and deleting data that I would need to keep. (One marco I have, saves the file and then saves over a back up file aswel- (just in case there is an issue with the original, I'll always have a fallback) I would want to be able to access the actual files myself as well to add and change things as the files grow. I have locked the cells I dont want them to acess, and installed different 'save' macros throughout so they can save the files. You do not need to create, change or add anything. I just need the files on a web page, and useable. The reason why I want them on a web page is because I don't want the company to have access to and to be able to save the original file. This way they can rent the file tracker off of me per month, and access everything only online.
