JSON Extractor

A JSON extractor tool extracts JSON (JavaScript Object Notation) from a string of text, allowing for easy extraction and analysis of JSON.

Use Ctrl + k + "Tools" to quickly access all tools.

The JSON Extractor tool is designed to extract structured JSON data from non-structured sources. This tool is particularly handy for web scraping scenarios where JSON or JSON-like structures are embedded within HTML or other document formats.

Use Cases

  1. Web Scraping: When extracting data from websites, it's common to find JSON structures embedded within HTML scripts or inline scripts. Our tool can pull this structured data out for further analysis or usage.

  2. Document Parsing: If you have text files or documents that contain embedded JSON structures, this tool can extract them, saving time from manual parsing.

  3. Data Migration: If you are transferring data between systems and only need the structured JSON data, the extractor tool can be a lifesaver.

  4. Research & Analysis: For researchers who frequently encounter non-structured data with embedded JSON, this tool simplifies the process of data extraction for analysis.

How to Use

  1. Input Data: Copy and paste the non-structured data into the tool's input box. For instance, you might paste in an HTML snippet:

    document.addEventListener("DOMContentLoaded", function(event) {
      window.dataLayer = window.dataLayer || [];
      function gtag(){dataLayer.push(arguments);}
      gtag('js', new Date());
      gtag('config', 'UA-12345678-1', {
        "custom_map": {
          "dimension1": "sessionId"
  2. View Results: The tool will display the extracted JSON structure. For the above example, you would see:

        "custom_map": {
          "dimension1": "sessionId"

Tips & Considerations

  • Avoid Overloading: For larger files or data sources, consider breaking them down into smaller chunks to prevent overloading the tool and ensuring faster responses.

  • Security: Always ensure that any sensitive information is removed or redacted before using online tools.

By incorporating the JSON Extractor into your workflow, you can seamlessly parse and extract embedded JSON data from non-structured sources, enhancing productivity and accuracy.
