Your file never leaves your computer. Parsing happens in the browser, in a background thread. The page's security policy forbids sending data to third-party addresses — you can check this in the developer tools. After the first visit the app keeps working offline.

What it does

Formats

Each format has its own page with details and fixes for the usual problems:

FAQ

Is my file really not uploaded to a server?

Right. Parsing happens in your browser, in a background thread. The page's security policy forbids sending data to third-party addresses, and you can see this in the developer tools. Turn the internet off — the app keeps working.

Do I need to install anything?

No, just open the page and drop a file on it. For use without a browser and without a network there is a Windows version — a single file that needs no installation.

How large a file can it handle?

DBF, CSV, XML, SQLite and Access files can be practically any size: they are read in pieces, not whole. JSON and Excel sheets are parsed into memory, so for them the limit is a few hundred megabytes.

How much does it cost?

For personal use — nothing: the web app and the Windows version are free, with no registration and no time limit. Organizations need a license — leave a request and we will propose terms.
