CSV to JSON Conversion Tool

This workflow is designed to automatically convert uploaded CSV files or text data into JSON format, supporting multiple input methods and intelligently parsing delimiters to ensure data accuracy. The conversion results are returned via API response, and in the event of an error, detailed notifications are sent to a Slack channel for real-time monitoring. This tool simplifies traditional data processing workflows, enhances response speed and stability, and lowers the technical barrier, making it suitable for software developers, business operations, and data teams to efficiently perform data format conversion and integration.

Workflow Name

CSV to JSON Conversion Tool

Key Features and Highlights

This workflow automates the conversion of uploaded CSV files or raw CSV text data into JSON format. It supports multiple input types—including file uploads, plain text, and JSON-formatted requests—and intelligently detects delimiters (comma or semicolon) to ensure accurate data transformation. The conversion results are returned via API response. In case of errors, detailed error information is provided and simultaneously sent to a designated Slack channel for timely monitoring and resolution.

Core Problems Addressed

Traditional CSV data processing and conversion often require manual operations or additional programming, resulting in cumbersome workflows prone to errors. This workflow automates the CSV-to-JSON conversion process, simplifying data handling, improving API response speed and stability, and effectively reducing technical barriers and operational risks.

Application Scenarios

  • Rapid conversion of CSV data files to JSON format for downstream system consumption
  • Automated integration of CSV data uploaded by clients or partners
  • Development of API endpoints offering online CSV-to-JSON conversion services
  • Internal enterprise data processing automation to streamline format conversions

Main Process Steps

  1. Receive POST requests via a Webhook node, supporting binary file uploads or text data
  2. Use a Switch node to determine data source based on request content type (file, plain text, or JSON)
  3. Extract binary data from files using the “Extract From File” node
  4. Convert plain text data into string format via the “Change Field” node
  5. Parse CSV text using a code node “Convert Raw Text To CSV,” supporting comma or semicolon delimiters
  6. Validate the conversion result for errors using the “Check if Value” node
  7. Aggregate data and return JSON-formatted results through the “Success Response” node if validation passes
  8. On error, return error details via the “Error Response” node and invoke the “Send to Error Channel” node to notify relevant personnel through Slack

Involved Systems and Services

  • n8n Automation Platform (core nodes)
  • HTTP Webhook (for receiving CSV upload requests)
  • Slack (for error notification delivery)
  • Built-in code nodes (for CSV parsing and processing)
