Frequently Asked Questions
How does the converter infer data types?
It checks non-empty values across each column: pure digits become INTEGER, decimals become REAL, and text strings become TEXT.
How are single quotes escaped in SQL strings?
Single quotes are safely escaped using standard SQL double-single quotes (' -> '') to prevent syntax errors.
