FAQ
Is my data uploaded?
No. Parsing, field detection, chart rendering and PNG export all run locally in your browser.
Which JSON structure should I use?
Paste any JSON document. The tool scans root arrays, nested arrays and equal-length column arrays, then lets you select the data path to chart.
Can timestamps be shown as dates?
Yes. The X axis supports second or millisecond timestamps, ISO date strings, local or UTC timezones and custom date format patterns.
Can I save chart settings?
Yes. Export a configuration JSON without raw data, then import it for another dataset with matching fields.
How many rows are supported?
The first version supports up to 5,000 rows to keep editing and chart interactions responsive.
