Microsoft Excel

APIs for automating, integrating, and extending Microsoft Excel functionality including workbook management, data manipulation, charting, and formula execution through Microsoft Graph REST APIs.

agent native

Reference-quality API operations across every facet — a rich contract, published governance, transparent operations, and machine-readable commercial terms.

Kin Score

API Evangelist profiles Microsoft Excel the way a machine reads it — 67 machine-readable artifacts across 11 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Microsoft Excel scores 71.5/100 (exemplar), with a separate agent-readiness read of 74/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Microsoft Excel

Each block below is one kind of artifact we hold for Microsoft Excel. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 11

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Arazzo Workflows 12

Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.

Multi-step API workflows described with the Arazzo specification.

Microsoft Excel Append a Row to a Table

Resolve a table on a worksheet, confirm its column shape, append a row, and read it back.

ARAZZO

Microsoft Excel Build a Chart from a Data Range

Verify a source range has data, create a chart over it, and confirm the chart exists.

ARAZZO

Microsoft Excel Flatten a Table into a Plain Range

Snapshot a table's rows and columns, convert it to a static range, and read the flattened cells.

ARAZZO

Microsoft Excel Create a Worksheet and Seed It with Data

Add a new worksheet to a workbook, write a header and data block into it, and read it back.

ARAZZO

Microsoft Excel Discover Workbook Structure

Open a session and inventory a workbook's worksheets, tables, named items, and charts.

ARAZZO

Microsoft Excel Write Through a Named Range

Resolve a workbook's named items, read the range a name points at, and write values through it.

ARAZZO

Microsoft Excel Sort, Filter, and Total a Table for Reporting

Resolve a table's columns, sort it, filter a column, and switch on the totals row.

ARAZZO

Microsoft Excel Delete a Table Row by Index

Read a table's rows, delete one by its zero-based index, and confirm the removal.

Microsoft Excel Read, Write, and Verify a Cell Range

Open a persisting session, read a range, write new values, and read the range back.

ARAZZO

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Model Context Protocol servers that expose these APIs to AI agents.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Notable capabilities this provider offers.

Workbook Sessions

Persistent and non-persistent sessions for efficient API operations.

Cell Range Operations

Read, write, and format individual cells or ranges of cells.

Table Management

Create, update, sort, and filter structured tables.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Examples 7

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Security Posture 4

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
