Things worth knowing

Spreadsheet copy-paste is tab-separated, which is detected automatically.
Cell contents are HTML-escaped, so text containing < or & renders correctly.
This reads the pasted text, not the .xlsx file — formulas and formatting are not included, only the values.

Questions

Frequently asked

Can I upload an .xlsx file?

Not directly — .xlsx is a zipped XML format. Open it in your spreadsheet application, select the cells, copy, and paste them here.

Is my data uploaded anywhere?

No. Every tool on JSONWorks runs entirely in your browser using JavaScript. Your input is never sent to a server, never logged and never stored. The simplest proof is to disconnect from the internet — the tools keep working. The site does load Google Fonts and a Google Analytics page-view tag, so you will see those two requests in your network tab, but neither receives anything you type or paste.
