I have a client that has developed an Excel spreadsheet to calculate various statistics using VBA Script (Excel/VBA is not my forte to say the least). He wants me to create a web front-end for this (I will be using PHP / CakePHP) that will have a simple form for inputting cell values, will query the spreadsheet and return the values for display on the website.
The client does not want to convert the Excel/VBA script to another language - he wants to keep it in a 'silo' and just have the website query the existing script.
Is this possible? Any libraries that can help? How could I go about this?
