What’s new in version 1.9.0

Updated on May 04 2021

Version 1.9.0:

Big update! We have new tools and many exciting improvements!

New features
  • Added JSON to CSV: many options to customize your needs (delimiter, auto-detect array from object, quote escape, etc).
  • Added CSV to JSON: support swap column/row, header, and custom delimiter.
  • Added Hash Generator: support MD5, SHA1, SHA256, SHA512, and many other popular hash functions.
  • You can now change the font size with ⌘+, ⌘-, ⌘0. You can even change the font with ⌘T or using the View → Font menu.
  • HTML Preview: added "Open in browser" button, so you can quickly preview the HTML in your favorite browser with your favorite Dev Tool.
  • Handle big files: Formatter/Encoder tools will now handle big files better. You will be able to store the output as a file (instead of crashing as the previous version).
  • Added "Save to file…" to the right-click menu in most of the output text boxes.
  • Clicking to the status bar icon will now close the DevUtils window if it is currently active.
  • The Unix Time Converter now automatically detects the input when you use the "Clipboard" button, no more manual select!
  • The Number Base Converter tool now automatically trim unnecessary white space and new line characters from the input.
  • The Base64 Encode/Decode tool now automatically removes the data notation (data:text/svg;base64,...) from the input when decoding. You can disable this behavior using the gear icon.
  • The UUID Generate/Decode tool now generates 100 records by default (previously, it was 1).
  • You can now minify the output of YAML to JSON and CSV to JSON tool.
  • You can now right-click → Save output to file... from most of the output text boxes.
  • Added an option to allow crash logs and anonymous analytics data to be sent to DevUtils. This is opt-in only, you can enable it in the Preferences panel (that would help me a lot to identify issues early, thanks! ?).
  • Fixed the CSS Beautify/Minify tool not working correctly with CSS variable and media query.
  • Fixed the encode/decode tools not persisting the user-selected option across app restarts.
  • Fixed app freeze when using the "Clipboard" button while having a large data in your clipboard.
  • Changed the output format control of the Text Diff Cherker Tool to use a pop up menu.
