The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About JSON Workbench

JSON Workbench is a local-first developer tool for large JSON, JSONL, and NDJSON files. Open a file, a JSON tab, or a captured response and explore it as a tree or table without losing numeric precision. Profile structure, infer a JSON Schema, build reproducible transform pipelines (native steps, jq, and JSONata), run local DuckDB SQL, diff two payloads as an RFC 6902 JSON Patch (with a side-by-side visual view), and export JSON, JSONL, CSV, or TSV. It can also pretty-print any JSON page in place. Your source data stays in the browser. Works in Chrome and Edge 120+.
