Migration-tool classification worksheet (37 tools) for "Component Migration in Web Applications: A Systematic and Multivocal Review of Architectures, Tools, and AI-Driven Approaches"

Supplementary data for: Garcia, P. V. et al., "Component Migration in Web Applications: A Systematic and Multivocal Review of Architectures, Tools, and AI-Driven Approaches", Journal of Universal Computer Science (J.UCS), 2026. The file migration_tools_classification.csv contains one row per tool (37 tools: 11 AI-Powered Migration Assistants, 13 Specialized Transpilers, 6 AI Coding Assistants, 5 General-Purpose Code Converters, and 2 boundary/enabling-infrastructure cases). For each tool it records the category, migration scope, transformation mechanism, automation level, primary and supporting source URLs, snapshot date (2026-09-18), boundary status, and classification rationale. DATA_DICTIONARY.md describes every column; README.md gives provenance and limitations. Tools were discovered through two LLM-based channels and an author-curated seed list, and each candidate was verified manually against its primary source. Classification was performed by a single researcher; 13 of the 37 entries are marked as boundary-adjacent. Vendor pages may have changed since the snapshot date.
