Convert CSV Rows into Reviewable SQL INSERT Statements

How to Use This Tool

Generate deterministic INSERT statements with quoted-field parsing and visible row counts. Convert a header-row CSV into escaped SQL INSERT statements for a named table, preserving nulls, numbers and quoted text entirely in browser.

The work this page finishes

Turning hundreds of spreadsheet rows into safe quoted literals by hand is repetitive, while a single column mismatch can shift every value into the wrong field. The row-preserving workspace makes a correction repeatable without rebuilding a prompt or transmitting the source file.

Deterministic workflow

Parse RFC-style quoted CSV, validate identifier-shaped headers and table name, emit NULL for empty cells, preserve numeric literals and double embedded apostrophes in text. This page accepts at most 5,000 records and 2 MB of text; rejected items retain their row references while valid items remain available.

Why a dedicated interface helps

Review the generated script in a disposable database and transaction before production; the row comments keep malformed records out of executable SQL. Immediate recalculation and a stable export are useful when the same rule must be applied consistently across a list instead of explained one item at a time.

Assumptions

• The first CSV row contains SQL-safe column identifiers.
• Empty cells intentionally represent NULL.
• Numeric-looking cells should remain unquoted.

Retain the original source until the destination accepts the result; processing stays in this tab, although the device and installed extensions remain part of the user's security boundary.

Limitations and review boundary

It does not infer a CREATE TABLE schema, validate database-specific types, handle binary values or execute any statement. No supplied URL is requested and no pasted markup or code is executed; output is inserted through text-only DOM operations.

Verification and provenance

The implementation was checked against SQLite — SQL Language Expressions on 2026-08-26, with fixtures for a known answer, an invalid input and a batch-specific edge condition. The fixture creates three statements and escapes O'Neil as O''Neil.
