Column alignment stays explicit
Every VALUES row must have the same number of scalar values as the stated column list. The output includes the parsed table name and rows.

Map explicit INSERT columns to supported scalar VALUES rows without evaluating functions or expressions.

What this tool does
Bounded, explicit-dialect processing
This is not a SQL interpreter. Exactly one INSERT with an explicit column list and literal VALUES rows is accepted; SELECT sources, functions, defaults, and expressions fail.
Expressions are never evaluated
Functions, variables, subqueries, DEFAULT, and engine coercions are outside the literal conversion subset.
The parser runs locally under byte, statement, AST-node, depth, row, column, diagnostic, and output limits. It never connects to a database or resolves files and URLs.
