Miscellaneous




The miscellaneous category collects powerful tools that do not fit neatly into other categories but are equally valuable for everyday tasks.
Generate barcodes for retail or inventory, edit CSV files visually without Excel, convert RTF documents to clean Markdown, create strong random passwords, practice speed reading to improve comprehension, and generate realistic fake data for testing and prototyping—all directly in your browser.

The barcode generator creates Code 128, EAN-13, and other standard barcode formats as downloadable SVG or PNG files.
The CSV editor lets you view, filter, sort, and edit tabular data in a spreadsheet-like interface.
The RTF to Markdown converter strips formatting codes and outputs clean Markdown syntax.
The password generator creates cryptographically secure passwords with configurable length and character sets.
Speed reading trains you to read faster using RSVP (rapid serial visual presentation).
The random data generator produces names, emails, addresses, and other structured fake data for development and testing.

All tools in this category run entirely in your browser, which means your data—whether it is a CSV with customer records, a private document, or generated test data—never leaves your device.
The tools work offline after the page has loaded, making them reliable even without a stable internet connection.
No account or subscription is required for any tool in this category, and there are no file size restrictions imposed by a server.

Frequently Asked Questions

What barcode formats does the barcode generator support?

It supports Code 128, EAN-13, EAN-8, UPC-A, and Code 39.
You can download the barcode as an SVG or PNG file.

Is the password generator cryptographically secure?

Yes.
It uses the browser's Web Crypto API (crypto.getRandomValues) which produces cryptographically strong random values.

Can I open large CSV files in the CSV editor?

The CSV editor handles files up to several thousand rows smoothly.
Very large files (100,000+ rows) may be slow depending on your device.

What does speed reading training improve?

RSVP-based speed reading trains your eye to process words without back-tracking, potentially increasing reading speed by 20-50% with regular practice.

Can I use the random data for a production database?

No.
The random data generator is intended for development, testing, and prototyping only.
Do not use generated data as real customer records.
