Excel on the web
- Ensure rrc.levitizedlife.com is published and opens over HTTPS. The manifest points there.
- Open a disposable workbook in Excel on the web.
- Choose Home → Add-ins → More Settings → Upload My Add-in, select the downloaded
manifest.xml, then upload. - Open the task pane, select a header row plus data, and click Read Excel selection. Features 1 and 2 accept arbitrary column names through their mapping previews. Feature 2 can read separate left and right selections; other modules use their documented schemas.
- Run an analysis. Write results to new Excel sheet creates a separate sheet with the assumptions, parameters, and output; it does not replace input cells.
If the upload option is unavailable, your Office version or organization policy may disable sideloading. The standalone website remains available.
Windows desktop
Use Microsoft’s shared-folder catalog testing procedure or non-local-server debugging procedure. These are development installation methods, not deployment to your employer’s organization.
Data formatting
- One rectangular range, with nonblank unique column names on the first row. For Data quality, map the identifier, amount, date and category roles, then preview your rules; unused roles can remain unmapped.
- 10,000 data rows maximum. Excel selection additionally limits the range to 50,000 cells.
- Date columns must display
YYYY-MM-DD. For Excel dates, set the number format toyyyy-mm-ddbefore import. - Ratios use decimals or percentage strings.
0.65and65%both mean 65%;65means 6,500%. - Keep currency, scale (dollars versus thousands), valuation date, and gross/net basis consistent. Blank financial inputs are rejected, not silently treated as zero.
- Loss triangles use cumulative values, development columns such as
d12,d24,d36, and trailing blanks for immature origins.
Privacy and permissions
The add-in requests ReadWriteDocument because it reads your selection and creates result sheets. It performs those actions only on button clicks. This app has no data backend, sign-in, workbook upload, or browser persistence. Inputs remain in memory until the tab closes or reloads. Microsoft Office.js is requested from its official CDN in add-in mode. Cloudflare hosting adds performance and security telemetry. The workbench does not send entered table data to those services.
Exports can contain the data you entered and calculated results. Review your organization’s rules before handling employer/client information in any personal tool.
What is verified
Pure calculation and parser tests are supplied in the repository. Actual Excel-host sideloading and permission behavior require a supported Excel environment and have not been certified. No automated statutory deadline source or official regulatory capital formula is included.
