STEP 1
Connect Excel and MQTT
Save credentials in WEXTL once. We store them encrypted and reuse the authorization across every workflow [3]. No coding or API skills required.
Excel and MQTT Integration
Extend your MQTT other workflows with the built-in Excel node from WEXTL®. Trigger events from MQTT, add the Excel node where you need it in the flow, and let WEXTL®'s visual builder run the whole automation for you — smart decisions handled by AI, no coding skills required.

How to connect Excel to MQTT
Set up your Excel and MQTT integration in 3 simple steps [2] — no coding required. Up to 10 minutes setup.
STEP 2
Build a workflow
Paste selected Excel and MQTT nodes onto the canvas [4], or describe what you want and WEXTL wires the flow together with AI Builder.
STEP 3
Map your data
Choose which fields need to sync between Excel and MQTT. Use filters or leverage a JS custom code step in between — everything is on the canvas.
How does the integration between Excel and MQTT work in WEXTL?
WEXTL exposes actions and triggers for Excel and MQTT that help you connect apps and automate repetitive tasks [1]. A trigger is an event that happens, an action — a step that performs when the event has occurred.

MQTT modules
- Publish a messagePublish a message to a topic and wait for the broker to confirm it (QoS 1).M
- Watch messagesStart a workflow when messages arrive on the topics you subscribe to. Checks on your workflow schedule.M
Excel modules

Frequently asked questions
Common questions about connecting Excel and MQTT.
Connect your Excel and MQTT accounts once, pick a trigger in one app and an action in the other, then map the fields so data flows automatically between them. [3]
Example: when MQTT's "Watch messages" fires, WEXTL can "Aggregate to Excel" in Excel. Excel has 3 actions (including Aggregate to Excel, Create Excel, and Parse Excel); MQTT has 1 action (including Publish a message). Add filters and transforms between steps when you need them. [1]
Yes — the integration works in both directions. Use each app's triggers to start a workflow and the other app's actions to update it. [2]
No. Excel-to-MQTT automations are built visually on the canvas. You can optionally add custom JavaScript with Functions when you need advanced logic. [4]
Yes. Trigger-based automations start the moment Excel (or MQTT) fires a new event — webhook-backed apps run within seconds, and polling-only apps re-check on a schedule you control. [7]
A first automation typically takes 5–10 minutes: connect each app's credential once, drop a trigger + action onto the canvas, map the fields, and turn the workflow on.
You can build your Excel + MQTT automation on a 3-day trial with every feature unlocked. Cancel anytime. For your protection, a small deposit is charged to your card when your trial starts. It counts toward your first payment and is non-refundable. [8]
