convert Excel spreadsheet to online calculator

Convert Excel spreadsheet to an online calculator. The calculator must cover all functionality of the attached spreadsheet and must offer printing a report. The key is to provide a working, fully functional and aesthetic online calculator. The calculator must be secure (use Node.js flavor or similar) so that user can't just copy all the calculations and paste these into another webpage. The online calculator is to be placed on website build and published on Weebly, it only supports Html, CSS and Java Script. It doesn't support PHP etc. Use supported languages only. The attached Excel spreadsheet is a mock-up of what is required, the calculations don't work correctly but this is enough for this project. The online calculator is to cover all functionality and calculations of this spreadsheet. It must include: input values, calculations, drop boxes, loading chart, force diagrams, help pop up messages etc. Only the main tab from this spreadsheet is to be visible in the online calculator. Final layout of the webpage with the online calculator is to resemble this spreadsheet. The webpage must offer printing the calculations. The printout is to look the same, or nearly the same, as the main tab of the attached spreadsheet. An example of html online calculator is: [login to view URL] - it does the job but aesthetically looks poor. If you have a license for [login to view URL] or something similar then this project should be even easier for you. Note: you must have similar experience in creating online calculators/charts. You will be required to provide links to examples of your work. By bidding for this project you agree that you will transfer all rights to the created online calculator to me - so that I have no problems with officially using it etc. You will have to sign a non-disclosure agreement where you agree to this (e.g. that you will not give away, sell, pass on, show etc anything that you create under this project). If we both find this co-operation satisfactory you will be asked to price on other projects. Let me know if you have any questions. Thanks.
