translate excel spreadsheet with some VB code macros to google sheet with java

I have an excel spreadsheet with some VB code macros that prompt the user for data input via popup screens, and output some data in a pdf format that I was looking at getting translated into google sheets. This macros that is being used to track a few different things for projects, and was interested in seeing what sort of ballpark timeframe and cost would be involved in creating a google sheets version. This way all of our field technicians can use it on site on a iPad/Phone/Whatever. (We use google apps for business, not o365) There are small popup windows where a user populates a few fields and this creates a row entry against a certain sheet, and also creates a pdf printout onto a template letterhead of that row entry. There are also options to print all entries to print all relevant entries stats' for the last week into a pdf report.
