  2. Specify your destination database table name and preferred batch size.
  3. Toggle CREATE TABLE generation according to your migration needs.
  4. Click Copy SQL Queries to run the generated statements in your database client.

Frequently asked questions

How does the converter infer column data types?
The parser samples values in each column. If all values are numeric without decimals, it assigns INTEGER. If decimals are detected, it assigns DECIMAL. Dates, timestamps, booleans, and variable-length strings are categorized automatically.
How are single quotes inside CSV text handled?
Standard SQL string escaping is applied: single quotes within text values are safely doubled (e.g. O'Connor becomes 'O''Connor') preventing SQL syntax breakage.
Can this tool process TSV or semicolon-delimited files?
Yes. You can select between Comma (,), Semicolon (;), Tab (\t), or Pipe (|) delimiters using the dropdown menu.
Why should I batch INSERT statements?
Batching rows into groups of 50 to 500 significantly reduces round-trip database transactions and executes orders of magnitude faster than single-row inserts.
Is my confidential business spreadsheet data uploaded anywhere?
No. The converter operates entirely inside your local browser memory using JavaScript. No files or rows are ever transmitted to an external server.
