CSV to JSON Converter with Error Handling & Slack Alerts

This n8n workflow provides a powerful API endpoint (/tool/csv-to-json) for transforming CSV data into JSON format. It accepts POST requests with file uploads (binary), raw CSV text, or JSON inputs, using a Switch node to route accordingly. For files, it employs the Extract From File node; for text, a custom Code node intelligently detects and handles comma or semicolon delimiters, ensuring flexibility across data sources.

Upon processing, data is aggregated into a clean JSON structure and returned with a 200 success response. Errors trigger a 500 response with details and simultaneously notify a configurable Slack channel (e.g., C0832GBAEN4) with execution logs and debug links, enabling rapid issue resolution. This setup minimizes downtime in production environments.

Ideal for developers integrating CSV-to-JSON conversion into larger automations, such as data pipelines, ETL processes, or API services. Benefits include time savings from built-in error resilience, no-code customization via n8n, and seamless Slack integration for team alerts. Test easily with CURL for files or raw data, making it perfect for IT teams handling diverse CSV sources in e-commerce, analytics, or reporting workflows.
