Turn code in Google Docs™ into highlighted code blocks: a monospace font, each keyword, string, number and comment in its color, on a shaded block.

HIGHLIGHT CODE IN YOUR DOCUMENT
Select the lines of code and press Highlight selection. CodeFill detects the language, or you pick one of 49, from Python, Java, JavaScript, C, C++, C#, SQL and HTML to Bash, Go, Rust, Kotlin, Swift and R. The lines become one block, a line per paragraph, so the code stays text you can edit, copy and search.

PASTE A SNIPPET
Paste code into the sidebar and insert it as a block after the paragraph your cursor is in.

YOUR LOOK
Light or dark; Roboto Mono, Source Code Pro or Courier New; sizes 8 to 14. Put the cursor in a block to change its look, or to highlight it again after you edit the code.

10 FREE, FULLY HIGHLIGHTED, THEN $9 ONCE
Your first 10 code blocks are free in total per Google account, fully highlighted. Highlighting a block again is always free. Then $9 once for unlimited blocks, with no subscription. Refunds within 14 days.
