Is converting XML to MariaDB 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 XML data keep its types in MariaDB?

Yes — that is the point. Whole numbers, decimals, dates and booleans are mapped to real MariaDB 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.

Convert XML to MariaDB

Upload a .xml file and get back a MariaDB 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 MariaDB

Generated from the converter's own MariaDB type mapping — this is what it actually emits, not an example.

Your data	MariaDB 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 .xml file

XML describes structure but not types, and nests arbitrarily deep, while a table does neither. The reader takes one specific slice of the document, and it is worth checking that the slice is the one you meant.

→Only the direct children of the row element become columns. A grandchild such as <address><city> has no text of its own at that level, so it arrives as NULL - flatten one level before uploading.
→Namespaces are reduced to local names, so <ns:order> and <order> are the same element here, and two elements differing only by prefix collide into one column.
→Attributes are read first and child elements second, so where a row carries both an id attribute and an <id> child, the child's value is what lands in the column.
→No XSD or DTD is consulted. Every value goes through the same inference a CSV gets, with the same refusal to guess at an ambiguous date.

What MariaDB gets, and how it differs

MariaDB and MySQL are close enough here that one dialect serves both, and picking MariaDB does not select a different code path: the script is byte for byte the one a MySQL conversion produces. The differences worth flagging are in what you do with it.

→The README packed beside the script names both engines in its load command, because the invocation is the same either way - the file is piped into a client rather than executed by the server.
→The CREATE DATABASE line in that README asks for utf8mb4_unicode_ci and not for utf8mb4_0900_ai_ci, which is MySQL 8's default. MariaDB has never implemented the 0900 collations, and unicode_ci is the one both engines have.
→Date-and-time columns are declared DATETIME rather than TIMESTAMP, so what loads is the wall-clock value the source held. No session time zone is applied on the way in, and none is applied when you read it back out.

Reading XML

→The row element is whichever child repeats — no configuration needed.
→Attributes become columns alongside child elements, so nothing on the row itself is left behind. What a table cannot hold is depth: only the row element and its immediate children are read, so nested structures need flattening by one level first.
→Empty and self-closing elements become NULL.

Writing MariaDB

→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;"
