Setup

Uploading a workbook​

  1. Go to App → Spreadsheet Sim.
  2. Click Upload .xlsx in the header.
  3. Select an .xlsx file from your computer.

The workbook opens in the IronCalc viewer in the main panel. Sheet tabs appear at the bottom — you can switch between sheets.

note

IronCalc is read-only. You cannot edit cell formulas in the browser. To change the model, edit the file locally and re-upload.

The screen is divided into two areas:

Sidebar (left):

  • Assumptions list with a + Add button
  • Outputs list with a + Add button
  • Reps input (number of simulation iterations)
  • Save Config / Load Config buttons

Spreadsheet (right):

  • Full IronCalc workbook view
  • Assumption cells are highlighted in blue
  • Output cells are highlighted in green

Saving and loading configs​

A config stores your list of assumptions and outputs for a given workbook, so you don't need to re-configure on each visit.

  • Click Save Config, give it a name, and click Save.
  • Click Load Config to restore a previously saved configuration.

Configs are saved to your account and persist across sessions.
