Every time I want to convert something, I search for it in google. And every time I found some ad-bloated and slow sites (if they even work), so I make this list of open source and good online converter tools.

Name of tool link to web demo, GitHub link to GitHub

• Multilingual:
  • Transform-tools (GitHub): JSON to a format for configuration files (TOML, YAML, etc.) GraphQL to struct, and more
• Programming languages:
  • Processing-p5-convert (GitHub): convert processing-java to p5js
  • TypeScriptToLua (GitHub) – convert typescript to Lua (work in the AST level, so it’s very reliable converter, and even has extensions to VSCode and WebStorm)
  • Icsharpcode-CodeConverter (GitHub) – Convert code from C# to VB.NET and vice versa
• Command line tools
  • Curlconverter (GitHub): convert curl command into programming language at your choice
  • Jc (GitHub): convert the output of popular command-line tools (like dig, ⁣ping, ⁣pip list,etc – at the time of writing this, it has around 180 different parsers) to JSON or YAML
• Markup:
  • Pandoc (GitHub) : convert from ANY markup format to another
  • Turndown (GitHub) : convert HTML to markup
• database
  • Quicktype (GitHub) : convert JSON to struct in a popular programming language
  • Sqlitebiter (GitHub) (offline only) : convert table file to SQL (support Excel, HTML, JSON, CSS, TSV, and a lot more)
    (I added it though it has no web online version because it really converts anything to SQL – in the GitHub example : sqlitebiter url "https://en.wikipedia.org/wiki/Comparison_of_firewalls" will extract all the tables from the Wikipedia page, then convert them to SQL database)
• images
  • webp2jpg (GitHub) – Use browser image functionality to converter images formats, resize, rotate, watermark, trim and rename images.
