What it does

Add Excel is an agent skill from microsoft/power-platform-skills, published by the product's own GitHub organization. Adds Excel Online (Business) connector to a Power Apps code app. Use when reading or writing Excel workbook data from OneDrive or SharePoint.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office, covering Excel spreadsheets and Cloud office suites. It works with Microsoft Excel, Microsoft OneDrive, Microsoft SharePoint and TypeScript. The repository describes itself as: A plugin marketplace for GitHub Copilot and other AI agents that provides Power Platform development plugins, including reusable skills, agents, and commands for building and… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 5ef4e4f. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
- Edit
- Write
- Grep
- Glob
- Bash
- LSP
- TaskCreate
- TaskUpdate
- TaskList
…and 3 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- make.powerapps.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Add Excel loads about 796 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 236 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~38
When it runs · the whole SKILL.md, loaded when a task matches: ~796

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Add Excel Online

Workflow

Check Memory Bank → 2. Gather → 3. Add Connector → 4. Configure → 5. Build → 6. Update Memory Bank

Step 1: Check Memory Bank

Check for memory-bank.md per shared-instructions.md.

Step 2: Gather

Ask the user:

Where is the workbook? (OneDrive or SharePoint)
Workbook file name
Which table(s) in the workbook to access

Step 3: Add Connector

First, find the connection ID (see connector-reference.md):

Run the /list-connections skill. Find the Excel Online (Business) connection in the output. If none exists, direct the user to create one using the environment-specific Connections URL — construct it from the active environment ID in context (from power.config.json or a prior step): https://make.powerapps.com/environments/<environment-id>/connections → + New connection → search for the connector → Create.

Excel Online is a tabular datasource -- requires -c (connection ID), -d (drive), and --table (table name in workbook):

bash

# OneDrive workbook
pa app add data-source --connector excelonlinebusiness -c <connection-id> -d 'me' --table 'Table1'

# SharePoint workbook -- dataset is the document library path
pa app add data-source --connector excelonlinebusiness -c <connection-id> -d 'sites/your-site' --table 'Table1'

Run for each table the user needs.

Step 4: Configure

AddRowIntoTable -- adds a row to an Excel table:

typescript

// OneDrive workbook
await ExcelOnlineBusinessService.AddRowIntoTable({
  source: "me",
  drive: "me",
  file: "MyWorkbook.xlsx",
  table: "Table1",
  body: { column1: "value1", column2: "value2" } // Flat object, NO "items" wrapper
});

// SharePoint workbook
await ExcelOnlineBusinessService.AddRowIntoTable({
  source: "sites/your-site",
  drive: "drive-id",
  file: "SharedWorkbook.xlsx",
  table: "Table1",
  body: { column1: "value1", column2: "value2" }
});

Key points:

source: "me" and drive: "me" for OneDrive personal files
For SharePoint, use the site path and drive ID
The body is a flat key-value object matching column headers -- do NOT wrap in { items: ... }

Use Grep to find specific methods in src/generated/services/ExcelOnlineBusinessService.ts (generated files can be very large -- see connector-reference.md).

Step 5: Build

bash

npm run build

Fix TypeScript errors before proceeding. Do NOT deploy yet.

Step 6: Update Memory Bank

Update memory-bank.md with: connector added, workbook/table configured, build status.
