Are my files uploaded anywhere?

No. Every step of the JSON → Pretty text conversion happens locally on your device. The files never leave your browser — you can verify this in your network tab.

What's the maximum file size?

There is no hard cap. SwiftConvert is limited only by the memory available to your browser tab, so very large json inputs may run slower on low-end devices.

About this converter

JSON → Pretty text

JSON → Pretty text — the fast, private way to turn JSON objects, arrays, or tabular records into clean UTF-8 plain text. Drag files in below and the converter runs entirely inside your browser tab. No sign-up, no upload, no size cap beyond what your device can handle.

Nested objects flatten predictably; arrays of objects become rows.
Numbers, booleans, and null are preserved as typed values.
UTF-8 plain text without hidden formatting.
Convert as many files as you like — each one triggers a direct download.

When to use this JSON to Pretty text converter

A dedicated json-to-pretty text converter is the fastest option when you need a clean .txt file without installing software, signing up, or waiting for a server round-trip. Typical uses include moving json content into pretty text without opening a heavy desktop app. Because everything runs in your browser tab, you can convert one file or a whole batch on a work laptop, a shared computer, a Chromebook, or even a phone — anywhere a modern browser runs.

How SwiftConvert converts JSON to Pretty text

SwiftConvert uses well-tested open-source libraries compiled to run inside the browser. When you drop a json file, it is parsed in memory, transformed into pretty text, and offered back to you as a direct download. No temporary copy is written to a server, no queue, no worker cluster — the CPU doing the work is the one in front of you. That means results are usually ready in seconds for small files, and speed scales with your device rather than someone else's free plan.

Tips for the best Pretty text output

For best results, start from a clean json source: fewer nested layers, embedded fonts where possible, and reasonable file sizes convert most reliably. If a batch stalls, split it into smaller groups so the browser can free memory between runs. On mobile, close background tabs before converting very large files. If a specific Pretty text setting matters to you — resolution, quality, page size — check the options exposed above the drop zone; SwiftConvert exposes the knobs that actually change the output, and leaves the rest on sensible defaults.
