JSON Input
Base64 Output
This converter validates JSON, formats it consistently, then encodes the JSON text as Unicode-safe Base64 in your browser.
This tool is built for developers, analysts, and data teams who need a fast, private way to convert structured data without installing a desktop app or sending files to a server.
Convert payloads into the format your endpoint, test fixture, or documentation needs.
Move structured records between config files, spreadsheets, and JSON-based systems.
Prepare clean examples for pull requests, support tickets, docs, and automated tests.
Keep everyday conversion work local in the browser instead of uploading sensitive data.
Input JSON example:
{
"user": {

"roles": ["admin", "editor"],
