JSON to TXT Converter
Convert JSON data into plain text. Choose a pretty-printed dump or a flattened key: value listing, ready to paste into any text editor.

Pro Tips
- •Pretty-Printed keeps the JSON structure with indentation, useful when you still want to see nested brackets
- •Flattened key: value produces one line per leaf value, using dot notation for nested objects and bracket notation for array indices
- •Empty objects and arrays are shown as {} and [] respectively in both styles
- •The whole conversion happens locally in your browser - nothing is uploaded anywhere
Most Popular
Most users choose Flattened key: value for quickly scanning deeply nested JSON as plain text
When to Use This Tool
Convert a JSON log entry or API response into flattened plain text for quick scanning without JSON syntax noise.
Export JSON configuration or data as a .txt file for tools, emails, or systems that only accept plain text attachments.
Paste flattened JSON key: value pairs directly into documentation or support tickets for a readable reference.
Flatten JSON into one value per line to make diffing two JSON documents in a plain text diff tool easier to read.
How It Works
Parse the JSON input using JSON.parse and validate its syntax
For Pretty-Printed output, format the parsed value with 2-space indentation
For Flattened output, recursively walk the structure, building a dot/bracket-notation path for each leaf value
Join every line together and display the resulting plain text, ready to copy or download

Frequently Asked Questions
What's the difference between the two output styles?
Pretty-Printed keeps the familiar JSON structure with braces and indentation. Flattened key: value produces one line per leaf value using paths like user.address.city or tags[0], which is easier to scan or grep for a specific field.
Does this work with arrays at the top level?
Yes. A top-level JSON array is handled the same way as any nested array - each item gets an index-based path like [0], [1] in the flattened style.
Is my JSON uploaded to a server?
No. The entire conversion happens locally in your browser using JSON.parse. Your data never leaves your device.
What happens with invalid JSON?
The tool shows the specific JSON syntax error so you can locate and fix the problem before converting again.
Can I convert the TXT output back to JSON?
The Pretty-Printed output is valid JSON and can be parsed by any JSON tool. The Flattened output is a plain-text summary and isn't meant to be parsed back into JSON.
