Why use this tool?

Automatically generate a JSON Schema from sample JSON without sending your data to a server. The tool infers types, properties, arrays and required fields to produce a reusable schema baseline.

100% local and secure

Your data stays on your device and is never sent to our servers.

Smart processing

Generate, convert, or validate technical data with purpose-built controls.

Supported formats

Technical formats and syntaxes suited to each generator, converter, or validator.

Save time

Get a clean, ready-to-use result in seconds without installing software or configuring a complex workflow.

Fonctionnement

How does this tool work?

The content is processed entirely in the browser by a shared engine. The transformation produces a typed resource compatible with Workspace so it can be chained with other operations. Nothing you enter or import is sent to Bethemesh during processing, and the result remains local for copying, exporting or pipeline use.

Use cases

Workflow

Use this transformation in a local pipeline and reuse the result immediately in the next compatible processing step.

Quick conversion

Process your content without installing software or uploading data to a remote online service.

Content preparation

Create a clean reusable output for a website, documentation, sharing or another local transformation.
