Load CSV or JSON data, inspect and filter it, run quick transformations, and export the result — a small data workbench that runs entirely in your browser.
Tip: Nothing you load leaves your device — safe for data you would not upload to an online converter.
Paste two versions of a text and get a highlighted, side-by-side comparison showing exactly what was added, removed or changed.
Tip: Comparing code or configuration files works too — the diff is line-aware, so re-ordered blocks show up clearly.
Profile, clean and chart CSV or JSON, and compare two files side by side -- text, code, data or images -- with inline differences and downloadable reports. Everything runs in your browser with no account and nothing uploaded, and your work in each tool is kept while you switch between them.
Clean, profile, transform, visualize and export CSV, TSV and JSON data entirely in your browser. Nothing is uploaded and no account is needed.
Compare text, source code, JSON, CSV data or two images side by side, with inline changes, an image slider and downloadable reports — all processed locally.
Data Lab parses and transforms tabular data in this browser. It is suited to survey exports, research data, contact lists, program records, budgets, and other material that should not be sent to an unknown conversion service.
Open CSV, TSV, and arrays of JSON objects; profile columns; find missing values; trim and normalize text; convert numbers and dates; rename or remove columns; filter, sort, and deduplicate rows; create basic charts; and export clean CSV or JSON.
This tool processes the files and text you select inside your browser. It does not upload their contents to Azad University. Your original files remain unchanged unless you explicitly download a new result.
Modern Chrome, Edge, Firefox, and Safari are recommended. Very large files may be limited by the memory available to your browser and device.
Your files stay on your device. The page itself still loads fonts and anonymous analytics from third-party services, so standard details like your IP address and page URL may be visible to them — as with any website.
Press 1–2 to switch tools. Each tool keeps its state while the studio stays open.
