FussyData is a service that wraps an API around Excel files, enforcing a schema in the Excel file. The data can be automatically converted into clean JSON, and passed into n8n for automation.
What is FussyData?
FussyData turns spreadsheets into APIs with schema validation.
Define the expected schema (columns, types, constraints).
Humans upload Excel files.
Workflow Overview
Here’s how the integration works:
Webhook node in n8n → receives a POST event from FussyData when a file is uploaded.
HTTP Request node → fetches the validated submission as JSON.
Code node (Python) → process, clean, or forward the data to other systems.
Flow:
Human Excel Upload → FussyData Schema Validation → n8n Webhook → HTTP Request → Code Processing
Invalid files are rejected with clear errors.
Valid files are converted into JSON and made available via API.
This ensures that human submissions are reliable, structured, and automation-ready.
