Scrape Structured Data with Thunderbit
Collect structured data from any website using Thunderbit’s Chrome extension: click AI Suggest Fields, then Scrape to capture tables, listings, and details across pagination and subpages. It also extracts data from PDFs, docs, and images, then summarizes, categorizes, and formats fields into a clean dataset.
Send your results to Google Sheets, Airtable, or Notion with free export options, or download CSV and JSON for your workflows. Use Scheduled Scraper to keep datasets fresh over time, and choose cloud scraping for faster runs or browser scraping for logged-in pages.
How to Format and Validate JSON Using Thunderbit
STEP 1Download and InstallDownload and install the Thunderbit Chrome Extension from the Thunderbit Chrome Extension Download Page. Once installed, log in or create a free account to get started.
STEP 2Open ExtensionOpen the Thunderbit Chrome Extension, then open the Json Viewer tool. Choose how you want to provide your JSON: use the "Paste JSON" tab to paste JSON into the "json_input" field, or use the "Upload JSON File" tab to upload a single .json file in the "json_file" field. Set your formatting preferences by selecting an "indentation" option (2 spaces, 4 spaces, or tab) and a "view_mode" option (text or tree) to control how the formatted output is displayed.
STEP 3Click the Format & Validate JSON ButtonClick the "Format & Validate JSON" button. Thunderbit will strictly validate your JSON and then either return a pretty-printed version using your selected indentation or provide an error report with a short message, a best-effort line and column location, and a suggested fix. Review the formatted result in your selected view mode, then export by copying the output text or saving it as a .json file for use in your workflow.
Learn how to view, validate, and format JSON data
Validate JSON and pinpoint errors
Paste JSON text or upload a .json file to check whether it is valid. The Json Viewer highlights syntax issues such as missing commas, mismatched brackets, or invalid quotes, helping you locate problems before they break an API call or automation. It is built for developers, analysts, and operations teams who regularly handle JSON payloads and need quick, reliable validation during debugging or data prep.
Format and edit JSON with readable structure
Convert messy, minified, or inconsistent JSON into a clean, indented format using 2 spaces, 4 spaces, or tabs. Edit values and nested objects while keeping the structure clear, with real-time feedback as you make changes. This is useful for anyone preparing configuration files, webhook payloads, or scraped data outputs who wants fewer formatting mistakes and faster reviews during collaboration.
Review JSON in text or tree view for faster QA
Switch between text mode for direct editing and tree mode for visual exploration of nested arrays and objects. Tree view helps you understand complex schemas, spot missing fields, and verify data types without scanning long blocks of text. This workflow fits product teams, QA, and data teams who need to inspect API responses, event logs, or exported datasets before sharing them with others.
Prepare JSON outputs for exports and automations
Use the formatted result as a clean source of truth for downstream tools such as scripts, ETL steps, or documentation. When you are working with Thunderbit exports like JSON downloads from web extraction, this viewer helps you confirm field names, nesting, and consistency before importing into databases or transforming for Google Sheets, Airtable, or Notion. It reduces rework caused by malformed JSON and unclear structures.
