JSON Flattener

Convert nested JSON into a flat object (for example, {"abc":{"bbb":123}} becomes {"abc.bbb":123}). This tool runs entirely in your browser and never sends your data anywhere.

JSON Flattener

Flatten nested JSON objects into a single-level object (dot-delimited keys). Nothing is uploaded.

About JSON Flattening

Flattening turns deeply nested objects into a single-level map of keys. It can make it easier to search, compare, and export JSON (for example, to spreadsheets or key/value systems).

Note: if your original keys contain the delimiter (like .), the flattened keys may be ambiguous.
