Convert Excel to MySQL
Upload a .xlsx or .xls file and get back a MySQL SQL script you can load straight into your database. Types are preserved rather than flattened to text. Free, no registration, up to 10MB.

How your data is typed in MySQL
Generated from the converter's own MySQL type mapping — this is what it actually emits, not an example.
| Your data | MySQL type |
|---|---|
| Whole number | BIGINT |
| Decimal (money) | DECIMAL(10,2) |
| Floating point | DOUBLE |
| True / false | TINYINT(1) |
| Date | DATE |
| Date and time | DATETIME |
| Short text | VARCHAR(255) |
| Long text | LONGTEXT |
| Binary data | LONGBLOB |
Working from an Excel file
"Excel" covers two entirely different file formats, and which one you have decides how much type information survives the conversion. It is worth checking what your workbook was actually saved as before you upload it.
- →Only .xls and .xlsx are recognised. A macro-enabled .xlsm, or a workbook saved as OpenDocument .ods, is refused before anything is read - save a copy as .xlsx first.
- →The two extensions take different code paths inside the reader: .xlsx through openpyxl, .xls through pandas and xlrd, and they do not recover the same amount of information from the file.
- →Sheet names become table names with every character outside letters, digits and underscores replaced one for one, so "Q1 Sales (2024)" arrives as Q1_Sales__2024: the space and the opening bracket each leave an underscore behind, and the trailing one is trimmed.
Loading the dump into MySQL
The download is a plain SQL script, so nothing in it depends on how you connect: the same file goes in through the command-line client, through a GUI import dialog or through phpMyAdmin. What is worth reading first is the handful of statements it runs before it creates anything.
- →Before the first CREATE TABLE the script issues SET NAMES utf8mb4, so the session decodes the file as UTF-8 whatever the client's own default character set is. The file itself carries no marker saying so.
- →The line after it turns FOREIGN_KEY_CHECKS off. That is there for the schema you are loading into, not for the script: it lets rows arrive in whatever order the tables came out of the source without a constraint that already exists rejecting them.
- →A true/false column is declared TINYINT(1) and its values are written as 1 and 0. MySQL's own BOOLEAN keyword expands to exactly that, so a client that does not special-case the width shows you a number rather than a boolean.
Reading Excel
- →Numbers, dates and booleans are read as Excel stored them, never converted to text and re-parsed.
- →Cell number formats are read out of .xlsx workbooks, so a column formatted as currency becomes a fixed-point decimal rather than a floating-point number — which is how money avoids acquiring a rounding tail. Legacy .xls is the exception: the xlrd path exposes no formats, so its currency columns come across as ordinary numbers.
- →A column formatted as a date becomes a date, not a timestamp at midnight; one formatted with a time keeps its time.
- →One sheet becomes one table. Empty sheets are skipped, and sheet names are sanitised for the target.
Writing MySQL
- →Tables are created as InnoDB with utf8mb4, so emoji and CJK text survive the load.
- →Backslashes are escaped, because MySQL treats them as escape characters by default.
- →Text columns of unknown length become TEXT rather than a guessed VARCHAR that could truncate your data.
- →Inserts are batched, and identifiers are capped at MySQL’s 64-character limit.
What you get
A ZIP containing dump.sql, plus a README with the exact command to load it. If anything about your data needed a judgement call, a _warnings.txt explains it.
Load this dump into MySQL or MariaDB: mysql -u USER -p DATABASE < dump.sql Create the database first if it does not exist: mysql -u USER -p -e "CREATE DATABASE DATABASE CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;"
Questions
- Is converting Excel to MySQL free?
- Yes. Files up to 10MB convert free with no account. There is a limit of five conversions per day per IP address.
- Will my Excel data keep its types in MySQL?
- Yes — that is the point. Whole numbers, decimals, dates and booleans are mapped to real MySQL types rather than everything becoming text. The mapping table above shows exactly what you get.
- Do you store my file?
- No. The file is written to a temporary directory, converted, and the directory is deleted as soon as your download has been sent.
