How to use this tool
Enter the page or campaign values you actually intend to publish, review the live preview or generated output, then copy/download only after checking it against your CMS and current platform requirements. OpenFileTools does not submit changes to search engines or social platforms.
Generated JSON-LD is only as truthful as the values you enter. Valid JSON does not guarantee rich-result eligibility.
JSON-LD
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "WebPage"
}
</script>Build reviewable JSON-LD for common page types from explicit fields, preview the object, and catch missing required local inputs without claiming rich-result eligibility. The workflow is designed as a repeat-use local workspace rather than a thin one-click page.
How OpenFileTools processes it
Local processing, explicit choices.
The browser generates previews, markup and deterministic text metrics from the values you enter. No website crawl or submission occurs.
Questions, answered.
Is my data uploaded?
No. Batch 4 planners, decision systems, SEO workbenches and local media composition tools process their working data in this browser tab.
Does this use live external data?
No. It generates or analyzes only the metadata/text you provide and does not crawl or submit your website.
