Free Online Tools — Reading Time, JSON to CSV Converter & More

These are single-purpose tools for tasks that come up often enough to be annoying but rarely enough that you don’t want to install software for them. Everything runs in your browser — paste in your data, get your answer, move on.

Writing and editing — The Reading Time Calculator estimates how long your article, essay, or report will take to read at average adult reading speed (238 wpm). Useful for blog posts, email newsletters, or any content where you want to set reader expectations upfront. The Words Per Page Calculator converts word count to estimated page count based on font size, line spacing, and margins — handy for print formatting or meeting page-count requirements.

Data conversion — The JSON to CSV Converter transforms structured JSON data into a comma-separated table you can open in Excel, Google Sheets, or any spreadsheet tool. It handles nested objects and arrays and gives you a preview before you download.

All tools work entirely in your browser. Nothing you paste or type is sent to a server.
