Connect Harpoon to Microsoft Excel
When New Client fires in Harpoon, your agent runs Add Table Row in Microsoft Excel. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.
What do you want Harpoon and Microsoft Excel to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Questions
Harpoon and Microsoft Excel, answered
What can start an automation from Harpoon?
Any of Harpoon's 9 triggers in the catalog, including New Client, New Contact, New Expense and New Expense Category. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Microsoft Excel when something happens in Harpoon?
Any of Microsoft Excel's 98 actions, including Create Folder, Create Workbook, Update Chart and Update Chart Component. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Microsoft Excel to Harpoon?
Microsoft Excel has no triggers in the catalog today, so automations start in Harpoon. If you need the other direction, ask: your agent reads Microsoft Excel's API documentation and adds it.
Do I have to build a connector for Harpoon or Microsoft Excel?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Harpoon and Microsoft Excel without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
