Excel add-in and would love to hear your opinion.
The aim is to let Excel users write formulas in simple IDE inside Excel. Instead of editing each of them in a formula bar you could just edit all formulas in one file (or for more advanced projects in multiple files).
What are the advantages? You could save your formulas to a separate file and import them through the add-in. This lets you easily share your formulas with others and add version control and code review to your project.
