What is Alljson?
AllJSON is a free, fast, browser-based tool for working with JSON. It validates messy JSON, lets you explore it as an interactive tree, and turns clicked fields into BigQuery / Snowflake-style SQL — all without sending data anywhere.
What it does Validate JSON, including a lenient parser (unquoted keys, trailing commas, single quotes). Auto-format and pretty-print JSON. Explore data as a collapsible tree with key filtering. Click a field to copy its dot-notation path; tick checkboxes in Select mode to build a SELECT statement. Auto-flatten an entire JSON document into SQL columns — updates instantly as you type. Generate BigQuery / Snowflake style expressions, including [OFFSET(i)] for arrays. Privacy Everything runs locally in your browser. Your JSON never leaves your device — there is no backend, no upload, no tracking of input data.
Who it's for Data engineers, analysts, and developers who deal with deeply nested JSON payloads from APIs, event logs, or warehouses, and need to quickly turn them into queryable SQL.
