Instant Data Scraper extracts data from web pages and exports it as Excel or CSV files

This tool does not require website specific scripts, instead it uses heuristic AI analysis of HTML structure to detect data for extraction. If the prediction is not satisfactory, it lets the user customize the selections for greater accuracy. This type of scraping technology is much more convenient, because it does not require large user created libraries of scraping scripts, which often become filled with outdated and redundant versions. This means that our scraping method works just as well with small and lesser known websites, as it does with global giants like Amazon. Also, our users do not need to have any coding, json or xml skills!
