application update - spreadsheet generator

I need a web form, preferably in PHP, similar to the link example: [login to view URL] where each saved form should generate a row from an EXCEL spreadsheet, in the end let me save this spreadsheet. I need to validate the fields, Date, Number, I'm from Brazil, so I need to consider our date and money format, if possible validate the CPF and CNPJ as well. Basically a spreadsheet generator. --- application update; attached the requirements.
