Hi, I am currently working with forms for surveys and I want to implement a simple possibility to make the users to add formulas for calculation of scores and relevance (to show ore hide) of questions.
I thought: Why should I implement my own calculation language when I can use a language every user may already know? So I came to the idea to use POI. I thought of parsing throw a formula and replacing variables within that formula with values - and then letting POI evaluate it. Is this feasible? Is it possible to only evaluate a formula without creating a temporary spreadsheet? Where in the javadoc of POI should I begin? Or does someone already has an example? Thank you, Philipp
