Paste a flat JSON object whose keys use dot-notation (`a.b.0`) or array brackets (`a.b[0]`) and rebuild the nested structure. Numeric segments are treated as array indices, everything else as object keys. Useful for parsing form-data style payloads, CSV → nested JSON, or undoing a flatten operation. Runs entirely in your browser — free, online, no upload.","category":"text","categoryName":"Text & Encoding","keywords":["json unflatten","unflatten json","flat json to nested","json from dot notation","expand flat json","nest json","json deepen","json unflatten online","json unflatten free","form data to json","json hierarchy builder","json restructure"],"badge":"Transformer","url":"https://myaitools.net/json-unflatten","inputs":[{"type":"text","key":"json","label":"Flat JSON","placeholder":"{\"a.b.0\": \"x\", \"a.b.1\": \"y\"}","multiline":true,"monospace":true}],"outputs":[{"key":"nested","label":"Nested","multiline":true}],"invocation":{"webUi":"https://myaitools.net/json-unflatten","api":null,"notes":"Currently invoked via the web UI at `webUi`.
