What file formats are supported?

You can paste raw CSV or TSV text directly, or upload .csv, .xls, and .xlsx spreadsheet files.

Which Schema.org types can I generate?

Currently, the tool supports generating structured data for Articles, Products, and Events.

How do I map my spreadsheet columns to schema properties?

The tool automatically maps standard column headers (like name, description, sku, price, startDate) to the corresponding JSON-LD properties based on the selected schema type.

What is the Public Page URL used for?

If provided, the tool appends this URL to a Google Rich Results Test link, allowing you to validate the structured data against your live page instantly.

Can I generate multiple JSON-LD items at once?

Yes, by keeping the 'Generate One Item Per Row' option enabled, the tool will output a distinct JSON-LD object for every row in your spreadsheet.
