Can I open the generated CSV in Microsoft Excel?▼

Yes, our CSV output complies with the universal RFC 4180 standard, which opens directly in Excel, Google Sheets, and Numbers.

How are commas and quotes handled inside data fields?▼

Fields containing commas are enclosed in quotes, and internal quotes are escaped by doubling them according to RFC 4180 rules.

What if some objects in the array have missing keys?▼

Missing keys are safely rendered as empty string fields ("") to keep table column alignment perfectly intact.

Is my data sent to any third-party server?▼

No. The entire JSON parsing and CSV export operates 100% locally inside your web browser.
