Discovery
Map your JSON before you build on it
Upload up to ten JSON files, however deeply nested, and get back three files: a data dictionary with what each field probably means, a lineage map of which objects sit inside which, and a JSON Schema with probable data types.
They're read in memory to make the three outputs and dropped as soon as the results come back to you. Nothing from them is saved to disk or a database, or written to our logs, and we don't keep a copy of the results either, so download them before you leave this page.
To word the meanings, field names and types (never the values in them) are sent to Anthropic's Claude, which doesn't train on them.
