Open your Kindle file

Your file stays on this device. This page reads it in your browser: nothing is uploaded, nothing is stored, and you do not need an account. For a vocab.db, the page first loads a SQLite reader (sql.js) from lexpad.app.

Or drop the file here.

Where the Kindle keeps your words

  • vocab.db: every word you looked up in the dictionary while reading, the list Kindle calls Vocabulary Builder. It is in the system/vocabulary folder.
  • My Clippings.txt: your highlights, notes and bookmarks, in the documents folder.
  • Connect the Kindle to a computer with its USB cable; it opens like a USB drive. Copy the file to your computer, then choose it above.
  • If you do not see the system folder, show hidden files: on a Mac press ⌘ ⇧ . in Finder; in Windows File Explorer choose View, then Show, then Hidden items.

The tool needs the file itself, so it works with a Kindle e-reader. We do not know of a way to copy the Vocabulary Builder out of the Kindle apps for phones and computers.

What you download

Both files are UTF-8 CSV with a comma between fields and quotation marks around any field that holds a comma, a quotation mark or a line break.
FileWhat is in itImport it in
kindle-words-anki.csvOne row per ticked word: Word, Sentence, Book, Author, Language, Date (of the latest look-up, from vocab.db). Four settings lines at the top tell Anki the separator, whether the file has HTML, the tag kindle and the column names.Anki 2.1.54 or later: File, Import
kindle-words-lexpad.csvA word,meaning heading, then one row per ticked word. The meaning column is empty: a Kindle file holds no meanings.Lexpad: Settings, Import & export, Import words

Only the words you tick go into the files. The tool never adds a word, a meaning or a translation: everything in them comes from your Kindle file.

Import the file into Anki

  1. In Anki on a computer, choose File, then Import, and pick kindle-words-anki.csv.
  2. Anki reads the settings lines at the top: comma as the separator, six columns, and the tag kindle on every note.
  3. Choose a note type and deck. With the Basic note type, map Word to Front and Sentence to Back, or keep the sentence on the front as a clue.
  4. Choose Import.

The settings lines follow the Anki manual’s file headers, which Anki 2.1.54 and later read (Anki manual, text files). With bold turned on, the file uses HTML so the word shows in bold in its sentence.

Bring the words into Lexpad

  1. In Lexpad, open the notebook for the book’s language, then Settings⁠, Import & export⁠, Import words⁠.
  2. Choose kindle-words-lexpad.csv. Words already in the notebook are skipped and counted.
  3. Open a word and choose Improve with AI to fill in the meaning, examples and pronunciation, or write the meaning yourself.

Each word starts in box 1 of five Leitner boxes and comes back on a schedule: 1, 3, 7, then 21 days, and longer once it is mastered. A miss brings it back today.

Want each word’s book as its topic? Import the original vocab.db or My Clippings.txt in Lexpad instead: Lexpad then brings in every word, with the book as the topic. Lexpad reads vocab.db on its server, so that import needs a connection. This page is for when you want only the words you tick.

How this page reads your file

  • A vocab.db is a small SQLite database. The page reads its WORDS, LOOKUPS and BOOK_INFO tables and shows one row per word: the dictionary form the Kindle stored (the form you looked up is one tick away), the sentence from your latest look-up, and the book.
  • Words the Kindle marks as mastered carry a tag, and you can hide them.
  • From My Clippings.txt, highlights become rows; notes and bookmarks are left out. Highlights longer than four words are passages, so they stay hidden until you show them. The same highlight twice in one book is one row.
  • The SQLite reader is sql.js 1.14.2 (MIT licence), served from lexpad.app. It is fetched only when you choose a vocab.db.
  • Nothing is sent or saved: no upload, no cookies, no storage in the browser. Close the tab and the page forgets the file.

Good to know

Questions

Is my Kindle file uploaded?

No. The page reads the file in your browser and keeps nothing. The only thing it downloads is the SQLite reader, from lexpad.app, when you choose a vocab.db.

Does it add meanings or translations?

No. A Kindle file holds the word, the sentence and the book, never a meaning, and this tool only rearranges what your file holds. In Lexpad, Improve with AI can fill in meanings after you import, or you add your own.

Why do I see sturdy when I looked up sturdier?

The Kindle stores both the form you looked up and its dictionary form. The tool shows the dictionary form; tick “Use the form you looked up” to switch.

Is it free?

Yes. There is no account, no limit and nothing to install.

Can I use it on a phone?

Yes, in a phone’s browser, as long as the file is on the phone. Copying it off the Kindle is easiest with a computer.
