Convert CSV to SQL INSERT Statements
CSV To SQL Insert for formatting or preparing SQL snippets.
Direct Answer
Use the CSV To SQL Insert tool when spreadsheet rows or exported CSV data need to become SQL INSERT statements for a database, migration, seed file, or test setup.
From CSV Rows to SQL INSERT Statements
The conversion follows a predictable structure: the CSV header row supplies the column list, and each data row supplies one VALUES tuple, but a few details need attention before you run the output against a real database.
- The header row becomes the column list in the generated INSERT statement, so header names need to match your actual table's column names.
- Each data row becomes one VALUES tuple, with text values quoted and numeric-looking values left unquoted.
- You supply or edit the target table name, since a CSV file doesn't carry that information on its own.
- Text values containing a single quote need that quote escaped, or the generated statement will have a syntax error or, worse, behave unexpectedly.
- Rows can be batched into one INSERT with multiple VALUES tuples, or split into one INSERT per row depending on what your database or migration tool prefers.
Data Type and NULL Pitfalls When Generating INSERTs
A CSV file has no concept of data types, every cell is just text, so the trickiest part of this conversion is deciding how ambiguous-looking values should be represented in SQL.
- A column that looks numeric can still contain a stray non-numeric value, like 'N/A' or a blank, that breaks a naive assumption that the whole column is a number.
- A value like '007' loses its leading zeros if it's inferred as a number instead of kept as text, which matters for IDs, zip codes, and product codes.
- An empty CSV cell, a cell containing the literal text 'NULL', and the actual SQL NULL keyword are three different things and need to be handled distinctly.
- Date-looking text in a CSV is still just text until it matches the exact format your column expects; assuming it will just work is a common source of import errors.
- Generating INSERT statements from a CSV you didn't create yourself carries the same injection risk as any unescaped user input, so quotes need to be escaped before the SQL is run.

Frequently Asked Questions
How does the CSV header row become the SQL column list?
Each header cell becomes one column name in the generated INSERT statement, in the same left-to-right order as the CSV, so column three in the header lines up with the third value in every VALUES tuple. If your actual table uses different column names than the CSV headers, you'll need to edit the generated column list before running it, since the tool has no way to know your schema's real names.
What happens to empty cells in the CSV, do they become NULL?
An empty cell is generally converted to the SQL NULL keyword rather than an empty string, since that's usually the intent behind a blank cell in a spreadsheet export. This is different from a cell that contains the literal text 'NULL' as a string, which should be treated as a quoted text value, not the SQL NULL keyword, unless you specifically want it interpreted that way.
Does the tool escape single quotes inside text values automatically?
Yes, a text value containing an apostrophe, such as O'Brien, needs its single quote doubled to '' so the generated SQL stays syntactically valid rather than breaking the statement early. Skipping this step is one of the most common ways a generated INSERT statement fails or, in a worse case, becomes an injection risk if the CSV data isn't trusted.
Can I generate one INSERT statement for all rows instead of one per row?
Yes, you can batch multiple rows into a single INSERT statement using multiple VALUES tuples separated by commas, which is usually faster to execute than one statement per row and is the more common style for seed files and bulk migrations. Some databases have a maximum statement size or row-count limit per batch, so very large CSV files may still need to be split into several batched statements.
How do I make sure a column with leading zeros like 007 doesn't get treated as a number?
That column needs to be explicitly treated as text so the generated SQL quotes the value as a string, preserving the leading zeros exactly as they appear in the CSV. Once a value like 007 is converted to a number, the leading zeros are permanently gone, so this decision needs to happen at generation time, not fixed afterward.
Is it safe to run generated INSERT statements from a CSV I didn't create myself?
Only if the quoting and escaping are handled correctly, since a text field containing a single quote, a semicolon, or SQL syntax could otherwise alter the statement in unintended ways, the same underlying risk as classic SQL injection. Review the generated statements, or at minimum confirm quotes are properly escaped, before running anything generated from an untrusted or externally sourced CSV against a production database.
What if my CSV has a value that's literally the text NULL?
A cell containing the text 'NULL' as characters is different from a truly empty cell, and the two need different treatment: an empty cell typically becomes the SQL NULL keyword, while a cell that spells out N-U-L-L should usually be quoted as a text string unless you specifically intend it to mean the SQL NULL value. Mixing these up silently changes your data's meaning.
Do I need to specify a table name before generating the statements?
Yes, the CSV only supplies column names and row values, not a table name, so you need to enter or confirm the target table name as part of generating the INSERT statements. This is also a good moment to double check that the CSV's column order and names actually correspond to the table you intend to insert into.
What happens to date columns in the CSV, do they get converted to a SQL DATE type?
Date-looking text is inserted as a quoted string in the generated SQL, not automatically converted to a database-specific date type, since the CSV has no type information for the tool to rely on. Whether that string is accepted depends on whether it matches the format your database and column expect, such as YYYY-MM-DD; a date like 03/04/2024 is genuinely ambiguous between March 4th and April 3rd without knowing the source locale.
Can I use this on a CSV that has commas inside quoted fields?
Yes, the CSV is parsed according to standard CSV quoting rules first, so a comma inside a properly quoted field is treated as part of that field's value, not as a column separator. This only works correctly if the field was quoted in the source file to begin with; an unquoted field containing a comma is genuinely ambiguous and will misalign the row.
How is csv-to-sql-insert different from manually building an INSERT statement?
This tool derives the column list and every VALUES tuple directly from your CSV file's header and rows, so it's built for converting existing tabular data in bulk. If you don't have a CSV and just want to type a handful of column names and values by hand, the sql-insert-generator is the more direct tool for that, since it doesn't require a file at all.
Will extra blank rows in my CSV create empty INSERT statements?
A fully blank row shouldn't generate a meaningless empty VALUES tuple, but it's worth checking the output, since a CSV with a trailing blank row from an export or a stray empty line can otherwise slip through. Running the file through a CSV cleaner first to remove empty rows avoids this entirely.
What database engines does the generated SQL work with?
The generated INSERT statement syntax (INSERT INTO table (columns) VALUES (...)) is standard across MySQL, PostgreSQL, SQL Server, and SQLite, but details like identifier quoting characters (backticks in MySQL versus double quotes in PostgreSQL) and date format expectations differ by engine. Double check identifier quoting if your column names contain spaces or reserved keywords.
