Latest version
Version 1.3
Released 21 May 2026 - 22.28 kBWorks with firefox 58.0 and laterOptions page — right-click the toolbar icon → Preferences (or about:addons → CSV beautifier → Preferences) to configure:
- Light and dark theme colors (font, background, border)
- Font size (10–14px)
- Row stripes on/off
- Align numbers to right on/off
Right-aligned numeric columns — columns containing only numbers are right-aligned automatically for easier comparison.
Dark theme support — table now adapts to the system color scheme; previous styling looked broken in Firefox dark mode.
3-state column sort — clicking a header cycles ascending → descending → original order.
Much faster on large CSVs — rewritten parser and DOM build; handles million-row files. Sorting no longer reads from the DOM.
Numeric values preserved as strings — leading zeros (e.g. "01234" zip codes) are no longer silently stripped.Source code released under MIT Licence
