Static Cache Wrangler – Headless Assistant

Static Cache Wrangler – Headless Assistant is a companion plugin for Static Cache Wrangler that converts cached HTML files into headless CMS-compatible formats for modern headless CMS workflows. g. sed, grep, awk, sort) and a willingness to explore the WordPress command-line interface.

This plugin enables composable, command-line interface tooling and IS NOT a point and click solution.

Testing Results

com (15-page WordPress site):

• ☑ 74% semantic conversion rate – 564 blocks converted to structured content

• ☑ 15 pages converted successfully to Sanity format

• ☑ 763 links preserved with proper structure and references

• ☑ 36 images tracked with migration metadata

• ☑ 14 accordions converted semantically

• ☑ 13 tables converted semantically

Top Conversion Rates Achieved:

* Simple pages: 86% semantic conversion

* Complex pages with mixed content: 74-82%

* Ultimate test page (141 blocks, 23 different Kadence block types): 52%

What Falls Back to HTML (requires custom hooks):

* Navigation menus (by design – preserves styling)

)

* Premium block libraries (Otter, Spectra – requires additional detectors)

Extensible Architecture

Unlike hardcoded solutions, this plugin uses a pluggable engine system where CMS targets can be registered via filters. Ships with Sanity® CMS support (unofficial) out of the box. It is technically feasible to target Contentful, Strapi, and others via extensions.
