Microsoft 365 add-ins · Excel assistant

Your data, questioned and worked on inside Excel

The HiloIntelligence pane opens inside Excel and works on the open workbook: it reads the ranges you point it at, writes values and formulas, builds pivot tables and native charts, and can analyse volumes a conversation could never hold.

What it does

An assistant that works inside the grid

The pane does more than comment on your numbers: it reads, writes and builds, with tools that match what Excel can actually do.

  • Read at the right scale

    The selection, a named range, a sheet's used range, or an overview of every sheet with its headers — never swallowing the whole workbook by default.

  • Write values and formulas

    Write into a range, lay down real formulas, format (font, fill, borders, number format, widths), create structured tables and set validation rules.

  • Pivot tables and charts

    Create and edit pivot tables and slicers, insert native charts — column, bar, line, pie, area, scatter — and adjust them afterwards.

  • Data tools

    Find and replace, sort, filter, apply conditional formatting, trace a cell's precedents and dependents, audit errors, recalculate.

  • Analyse very large volumes

    For what a conversation cannot hold, the assistant profiles a range without reading its detail, or runs an analysis in an isolated sandbox — up to workbooks of more than a million cells.

  • Check its own work

    With a model that can see images, the assistant can render the range or chart it just produced and visually verify the result.

Where and how

Deployed by your administrators

The add-in is deployed by manifest URL from the Microsoft 365 admin center, then assigned to a group.

  1. 01

    Excel on Windows, Mac and the web

    The manifest declares the desktop form factor; the web version is supported and needs one extra redirect URI in Entra for single sign-on. Older builds simply expose fewer tools, without errors.

  2. 02

    One admin-center deployment

    Your administrators paste the manifest URL into Integrated apps, then assign it to a group rather than to everyone. Allow 24 to 72 hours for Microsoft-side propagation.

  3. 03

    The same app registration as Outlook

    Each add-in deploys separately, but they all reuse the Entra registration already in place for the Outlook add-in — nothing new to create on your tenant.

  4. 04

    Access stays yours

    Sign-in uses the person's Microsoft single sign-on, and your administrators decide which groups may use the module.

Limits, stated plainly

What the add-in does not do

The assistant is built to announce what it cannot do rather than quietly work around it.

  • No VBA macros: neither running nor creating them.
  • No creating Power Query connections — refreshing an existing one, yes.
  • No sparklines, no SmartArt, no Solver-style multi-variable optimization, and no reading or writing legacy notes.
  • Reads are capped (100,000 cells per range): beyond that the assistant profiles or analyses rather than reading everything.
  • Undo restores the active sheet's contents and formulas as of the start of the turn, but not formatting.
  • Sheet protection set by the assistant carries no password: it prevents accidental edits, not determined ones.
  • By default edits apply immediately; turn off auto-apply to confirm each change.
Deployment

Getting the Excel add-in to your teams

Four steps, done once by your Microsoft 365 administrators. Nothing to install on anyone's machine.

  1. 1

    Copy the manifest URL

    It is shown inside your instance under Admin → Settings, with a copy button. It ends in /excel/manifest.xml.

  2. 2

    Open Integrated apps

    In the Microsoft 365 admin center: Settings → Integrated apps → Upload custom apps, then “Provide a URL for the manifest”.

  3. 3

    Assign to a group

    Rather than to everyone — that is what lets you open the add-in to a pilot team before widening it.

  4. 4

    Let Microsoft propagate

    Allow 24 to 72 hours before the button appears in everyone's ribbon. The delay is Microsoft's, not the platform's.

Each add-in deploys separately. For use in Excel on the web, a redirect URI must also be added to your Entra app registration — without it single sign-on fails in the browser while the desktop works. Our team supplies it with the manifest.

Try it on your own files

Create your workspace and deploy the add-in from the Microsoft 365 admin center. Your administrators choose who gets access.
