💡 Tip: Format your data using the guide above. For quick conversion, use AI or a spreadsheet tool to generate comma-separated field names for simple text fields.
Yes, the tool is 100% free. There are no subscriptions, account requirements, or “pro” versions needed to generate your JSON schemas.
No, your privacy is a priority. All processing happens instantly, and your input data is never saved, tracked, or stored on our servers after the JSON is generated.
This specific generator is engineered exclusively for the Custom Post Type (CPT) workflow. While CCTs are useful for high-volume data, this tool focuses on providing perfectly structured JSON for the standard WordPress wp_postmeta tables used by CPTs.
Generic AI models often hallucinate the specific nested array structures required by JetEngine, leading to import errors. This tool follows strict, hard-coded formatting rules designed specifically for Crocoblock compatibility, ensuring a perfect import every time without guesswork.
Once you have copied the valid JSON output from the generator, navigate to your WordPress dashboard under JetEngine > Skins Manager > Import Skin. select your file there to instantly deploy your meta fields to your selected Custom Post Type.
