Tool Changelog & Updates

v1.1.02026-06-12
  • Fix: Changed TIMESTAMP to DATETIME and DECIMAL to DECIMAL(10, 2) for more accurate type mapping.
  • Feature: Accurate number type mapping — integer values map to the language's native integer type, decimal values map to float/double.
  • UX: Updated module descriptions, How-to guides, and FAQ sections with multi-language support.
  • Fix: Fixed "Conversion complete" toast showing even when JSON parsing failed — now only shows success on actual completion, shows error message on failure.
