About Parsefy

Why privacy-first?

Most online converters work the same way: you upload a file, a server processes it, and you download the result. That is fine for a list of movie titles. It is not fine for an API response full of customer emails, a database dump, or a payroll export — and those are exactly the files developers most often need to reshape in a hurry.

The uncomfortable part is that you usually cannot tell what happens to the file after the upload. Is it deleted immediately? Logged? Retained for a "temporary" period that is never defined? For anyone working under a data processing agreement, an NDA, or plain common sense, pasting production data into an unknown server is a decision you should not have to make just to convert a file format.

Parsefy removes the decision. There is no upload endpoint, because there is nothing to upload to.

How it actually works

Every tool here is plain JavaScript running in your own browser tab. When you paste JSON or open a CSV, the parsing, flattening and file generation all happen in your device's memory. The result is handed back to you as a download generated locally — even the Excel workbooks are assembled in the browser.

You do not have to take our word for it. Open your browser's network panel and convert something: you will see no request carrying your data. Or go a step further and disconnect from the internet entirely — once the page has loaded, every tool keeps working.

The one thing we do collect is ordinary, aggregate site analytics so we know which tools people find useful. That is described plainly in our privacy policy, and it never includes the content you convert.

Who builds it

Parsefy is built and maintained by an independent developer who got tired of closing tabs on converters that wanted an account, an upload and an email address to turn one text format into another. It is free, it has no sign-up, and there is no paid tier holding the useful features hostage.

If a tool gets something wrong, or the format you need is missing, send a message — bug reports about real-world data are genuinely the most useful feedback we get.
