9 February 2024

ഒരു നിമിഷാർദ്രം കൊണ്ട്
സ്മൃതിപഥത്തിൽ നീയുണർന്നു.
നമുക്കൊരു ആൾരൂപം
നിൻ്റെയുള്ളിലുണ്ടെന്നുള്ള സത്യം
ശിശിരകാലം പോലെയെന്നിൽ

Export your Kindle book highlights

24 January 2024

If you want to export your Kindle book highlights without the page location and color information, you can follow these steps:

  • Export the content in any format you prefer.
  • Paste the content in Visual Studio Code or any other text editor that supports regular expressions.
  • Use the regular expression Highlight \(yellow\) - Location [0-9]+ in the Find and Replace tool to replace Highlight (yellow) - Location 01.
  • Replace all the matches with an empty string.

This will remove the unwanted details from your highlights and leave only the text you want to keep.
