JSONL Viewer and Editor with Diagram Visualization
ToDiagram reads every line of a JSONL file as its own record and lays the records out as an interactive diagram, in file order. Nested objects and arrays inside each record become connected nodes, so you can follow the shape of a log event or a dataset row at a glance and edit it in place.
Sign up freeVisualize JSON Lines as diagrams
Turn each line of a .jsonl or .ndjson file into a record on an interactive diagram. Nested fields become connected nodes, so deep structures stay readable.
Edit records, keep the format
Change values, rename keys or add fields on the diagram or in the tree view. ToDiagram writes the document back as JSON Lines, one compact line per record.
Find the broken line
If a line isn't valid JSON, the editor marks that exact line, so a bad record in a long file is quick to find and fix.
Validate every record
Attach a JSON Schema that describes one record and every line is checked against it. Generate a starting schema from your data in one click.
