Is converting Microsoft Access to SQLite 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 Microsoft Access data keep its types in SQLite?

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

Upload a .mdb or .accdb or .mde file and get back a SQLite file. Types are preserved rather than flattened to text. Free, no registration, up to 10MB.

How your data is typed in SQLite

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

Your data	SQLite type
Whole number	BIGINT
Decimal (money)	NUMERIC(10,2)
Floating point	REAL
True / false	BOOLEAN
Date	DATE
Date and time	TIMESTAMP
Short text	TEXT
Long text	TEXT
Binary data	BLOB

Working from a Microsoft Access database

The reason people search for this one is usually not the file, it is the software. Converting here needs no copy of Microsoft Access, no Office licence and no Windows machine anywhere in the process.

→Reading happens on the server through the mdbtools utilities, so the ACE and Jet ODBC drivers are never involved: no "provider is not registered on the local machine", and no 32-bit versus 64-bit driver mismatch.
→You do not need Access at your end to check the result either. The preview lists the tables, columns and detected types before you download anything.
→Nothing is installed or run on your own machine, and the server's temporary copy of your database is deleted as soon as the download has been sent.

What the .sqlite file looks like inside

The output here is a real database rather than a script, so the interesting question is not how to load it but what SQLite did with the types on the way in. Its storage classes are looser than the declarations the file ends up carrying.

→Names are carried over exactly as they were, with none of the sanitising the script targets apply: a table called Sales Report keeps its space and a column called Order ID keeps its own, so your queries have to quote them.
→Underneath the declared types sit only five storage classes, and NUMERIC affinity - what a decimal column gets - is the loosest of them: it normalises inserted text to whatever a plain INTEGER or REAL column would hold. The precision and scale in the schema are for a human reading it, not a guarantee SQLite enforces on the bytes; the Writing notes below cover what that means for money specifically.
→Declared type and stored type are different things here: a BOOLEAN column holds the integers 1 and 0, and a DATE column holds ISO text, because those are the storage classes SQLite actually has. Every client reads them back the same way.

Reading Microsoft Access

→Dates are exported in ISO form, avoiding the ambiguous 12/02/21 that Access tools produce by default.
→NULL and the empty string stay distinct.
→Access can hold dates outside the range it can represent. Those become NULL and the conversion tells you, rather than dropping them silently.
→Requires mdbtools on the server; if it is unavailable you get a clear error rather than a partial conversion.

Writing SQLite

→Columns get real declared types rather than everything being TEXT.
→Primary keys and NOT NULL constraints are preserved.
→A money column is declared NUMERIC(10,2), but that declaration does not stop SQLite’s own numeric affinity from converting the inserted value into a float once it lands, so 19.99 can come back with a rounding tail. Pick the DuckDB target instead when the exact decimal has to survive.
