Calculator Studio operates on the GRID spreadsheet engine, which differs slightly from typical spreadsheet software. While the GRID engine supports the vast majority of spreadsheet functions, a few specialized or rarely used features may not be available. Notably, GRID does not support scripting languages like Visual Basic for Applications (VBA) or App Script. However, it’s important to note that the engine fully supports 98% of all spreadsheet functions, and for most of the remaining cases, straightforward workarounds can achieve similar results.

Calculator Studio supports spreadsheet files from Microsoft Excel™ (xlsx), Google Sheets™ and flat CSV data files. You can link to these files in cloud drives such as Dropbox, OneDrive or Google Drive; provide a URL to the files; or upload them directly from your computer. You can also connect Notion databases and Airtable bases to your projects in Calculator Studio.

This is a great question, and the answer is no. Calculator Studio does not write back into your original spreadsheet when a calculator is interacted with or altered. Just think of your calculator or project as a protective layer between your spreadsheet and your viewers. You decide which parts of the spreadsheet you want to present, how you want it to appear, and who will see it. The spreadsheets you’ve connected to Calculator Studio will never be altered by changes made (by author or viewers) to the project.

Currently we do not offer any on-premise options and we do not plan to do so in the foreseeable future.

We take a serious approach to protecting our users and their data. First, we use industry-standard methods such as TLS and end-to-end encryption for all communications and data centers with acknowledged certifications. All user data is encrypted at rest to prevent any compromises in case of stolen hardware.

We have a private bug bounty program managed by Intigriti where we continually leverage their community of more than 70,000 security professionals to probe for weaknesses in our product. We engage in regular penetration tests where a select group of their researchers is tasked with probing the product and given extra information about system architecture to increase the chance of them finding weaknesses. This provides our engineers with information about security issues from trusted sources which are contractually bound to report and secrecy, allowing us to find and fix any issues before they are exploited. When vulnerabilities in existing features are reported, we treat them as a possible breach and initiate our internal breach review process.

Finally, we use CloudFlare to protect against denial of service attacks and many types of suspicious/malicious requests and to give us added ability to block out traffic from harmful actors.
