TXT to JSON Converter Online

Our free TXT to JSON tool is designed for developers, data analysts, and technical users who need to quickly convert raw text data into structured JavaScript Object Notation (JSON) format. With automated parsing and formatting, you can generate valid JSON files instantly.

Conversion Modes

  • Array of Lines: Ideal for simple lists. The tool will read every line in your text file and output a single JSON array where every item is a string representing a line.
  • Tabular Data (Objects): Perfect for TSV or comma-separated text dumps. The tool reads the first line to establish the JSON object "keys", and uses subsequent lines to populate the values, resulting in an array of structured JSON objects.

How to Convert TXT to JSON

  1. Upload Text Files: Drag and drop your `.txt` files into the workspace.
  2. Select Structure Mode: Choose between a simple string array or structured tabular objects based on your data shape.
  3. Convert: Click the process button. The tool will automatically parse the text and serialize it into beautifully formatted JSON.
  4. Download JSON: Save your new `.json` files to use in your APIs, configurations, or JavaScript applications.

100% Client-Side Processing

Data privacy is critical when working with structured information. Our TXT to JSON converter processes everything directly in your web browser. Your text and data are never sent to external servers, guaranteeing absolute privacy and instantaneous conversion speeds.
