✓ TestedWorks with CSV, Excel, Google Sheets → JSON-LD Schema
By dataclean.to team · 2026-02-05
Customer feedback generates Schema.org Review markup for products and services. Automated schema generation processes ratings, review text, authors, and dates. This tool converts spreadsheet data into structured JSON-LD that qualifies for review rich results.
The Problem
B2B companies maintain review data across feedback platforms, testimonial systems, and customer databases with inconsistent formatting. Star ratings, review content, reviewer information, and timestamps vary in structure. Manual schema creation for hundreds of reviews takes excessive time. Automated generation ensures consistent structured data while maintaining relationships to reviewed items, authors, and rating scales that follow schema specifications for search visibility.
