Is Nonogram Puzzle Generator - Create Unique Puzzles In Excel - UPDATED worth it if you’re shopping in Software Development?
If you are self-publishing activity books, planners, or puzzle collections on KDP, you know the bottleneck: finding a steady stream of unique, high-quality content that doesn’t look copy-pasted. Nonograms—also known as Japanese crosswords or picross—are a perfect fit for this niche because they require logical deduction rather than artistic skill, but generating them manually is painfully slow. The Nonogram Puzzle Generator from KDP Tools solves this by turning your Excel spreadsheet into an infinite puzzle factory. For $20, you get a tool that lets you batch-create distinct grids in various sizes, ready to be dropped into your next book design. This is the kind of utility that saves hours of manual labor, letting you focus on layout and distribution instead of staring at a blank grid.

What you’re actually buying
You are purchasing a specialized Excel workbook designed specifically for the creation of nonogram puzzles. Unlike generic spreadsheet templates, this tool is built to handle the specific logic of Japanese crosswords, allowing you to generate four distinct types of nonograms. The core value here is volume and variety: the system enables you to create an unlimited amount of unique puzzles in different sizes, which is critical when you are filling a 50-page activity book or a monthly planner.
The workflow is designed for KDP integration. Once you generate the puzzle images within Excel, you can directly insert them into your book design software. The tool supports the standard requirements for self-publishing, ensuring the output is clean and ready for print. It runs on Windows 10 and 11 with Excel 2010 or higher, making it accessible for most creators who already have a Microsoft 365 subscription. If you prefer to export your puzzles to PowerPoint for further formatting, that is supported as well, though PowerPoint is not strictly required for the generation process.

One specific detail stands out for those who have used similar tools: the emphasis on manual, individual generation. As one buyer noted in a Gumroad review, “It makes sense to make unique puzzles and have them done individually and manually.” This approach ensures that every puzzle in your book is distinct, avoiding the repetitive feel that can plague low-effort puzzle collections.
Why it’s on our radar
This tool is interesting because it addresses a specific pain point for KDP authors: the need for scalable, unique content. Many puzzle books fail because the puzzles are too similar or too easy to generate, leading to reader fatigue. By offering four types of nonograms and supporting various grid sizes, the Nonogram Puzzle Generator allows you to mix and match difficulty levels and formats within a single book.
The price point of $20 is also compelling when you consider the time cost of manual puzzle creation. If you are producing multiple books a year, the tool pays for itself in the first few hours of saved labor. It is a niche tool, but for anyone in the puzzle book niche, it is a high-leverage asset. The fact that it is an “UPDATED” version suggests the seller is maintaining the file for compatibility with newer Excel versions, which is a small but important detail for long-term usability.

What actually matters
Before you buy, confirm your software environment. The tool is built for Windows 10/11 and Excel 2010 and higher. If you are on Mac or using a web-based version of Excel, this tool will not work for you. Check your system requirements carefully. (Nonogram Puzzle Generator -)
- No Image Import: The tool does not generate nonograms from imported images. You are generating logic-based puzzles from scratch, not converting a photo into a grid. If you need image-to-puzzle conversion, this is not the right tool. (Nonogram Puzzle Generator -)
- PowerPoint is Optional: You only need PowerPoint if you want to export the puzzles to that format. The core generation and image insertion workflow happens within Excel. (Nonogram Puzzle Generator -)
- Digital Product Terms: As with all digital goods, this is a non-refundable purchase. If you encounter technical issues, the seller encourages you to contact them directly for support. (Nonogram Puzzle Generator -)
