NexusLabs Data Converter — 6 Format Tools

6 data tools in one popup — convert between structured formats, calculate timestamps, and handle number bases. Fully offline.

Stop jumping between online converters every time you need to reshape data. NexusLabs Data Converter puts 6 powerful, privacy-first format utilities into a single beautiful popup — right in your browser toolbar. Whether you need to restructure tabular data into a structured format, switch between configuration syntaxes, render formatted markup, translate between number systems, look up a point in time, or calculate file access rules — Data Converter handles it in one click without leaving your current tab. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ What You Can Do Paste comma-separated rows and instantly convert them into structured key-value output, or go the other way — drop in structured data and get clean tabular rows back. Headers are detected automatically, and you can copy the result with one click. Switch between two of the most popular configuration and data-interchange syntaxes. Paste one format, see the other rendered instantly. Handles nested objects, arrays, numbers, booleans, and null values with proper formatting. Write content using lightweight markup shortcuts — headings, bold, italic, strikethrough, code blocks, and inline code — then preview the rendered output or copy the generated markup directly. Enter any whole number and see it expressed in decimal, binary, hexadecimal, and octal simultaneously. Type in any field and the other three update in real time. Each value can be copied individually. Convert a point in time to its numeric representation and back. A single button captures the current moment, and you can edit either side to explore how dates map to their numeric equivalents. Calculate access-control rules by toggling individual checkboxes for owner, group, and other — each with read, write, and execute options. The numeric and symbolic representations update live, plus a ready-to-use terminal command you can copy directly. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 Privacy First This extension makes zero network requests.
