Question: I'm looking for a tool that can extract data from websites in JSON format, do you know of any options?

SingleAPI is a powerful option, using GPT-4 technology to convert any website into an API in a matter of seconds. It can extract data in JSON format, but also includes automated data scraping, data enrichment tools and API generation. It supports multiple data formats and includes features like automated proxy rotation, real-time webhooks and 24/7 uptime.

Another top contender is ScrapingBee, which controls headless browsers and proxies to scrape even JavaScript-heavy websites. It can produce formatted JSON output and run custom JavaScript code, so it's good for general web scraping and data extraction. ScrapingBee also offers a no-code web scraping option and a variety of pricing tiers based on API credits and concurrent requests.

For a more developer-oriented service, ScrapeNinja automates browser control, integrates with proxies and runs continuously. It's geared for complex web scraping jobs, so it's a good option for developers and data analysts who need to scrape data often. ScrapeNinja is integrated with RapidAPI for easy subscription and use.
