Is converting SQLite3 to XLSX 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 SQLite3 data keep its types in XLSX?

Yes — that is the point. Whole numbers, decimals, dates and booleans are mapped to real XLSX 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 SQLite3 to XLSX

Upload a .sqlite or .db or .sqlite3 file and get back a XLSX file. Types are preserved rather than flattened to text. Free, no registration, up to 10MB.

1Upload your file

Click to upload or drag and drop

CSV, Excel, SQLite, SQL, DBF (max 10 MB)

2Choose target format

How your data is typed in XLSX

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

Your data	XLSX type
Whole number	number
Decimal (money)	number
Floating point	number
True / false	boolean
Date	date
Date and time	date
Short text	text
Long text	text
Binary data	hex text

Working from a .sqlite3 file

The 3 in .sqlite3 is the version of the file format, not of your file, and it has not changed since 2004. A .sqlite3 and a .sqlite are the same kind of thing under two naming habits, and both are read the same way.

→db.sqlite3 is Django's default database name, and a Django database converts whole: django_migrations, auth_user and django_session are ordinary tables here and come across with everything else.
→Nothing is filtered on the way through, so if you only want the application tables it is easier to drop the framework ones in the target database after loading.
→The extension does not change how the file is read - it only has to be one the uploader recognises, and .sqlite, .sqlite3 and .db all are.

Sheet names and cell types

The workbook is generated rather than exported out of Excel, so every choice in it is one the converter made. The two that show up the moment you open the file are what the sheet is called and what type each cell turned out to be.

→The sheet takes the table's name cut to 31 characters, which is Excel's own limit for a tab, while the workbook file keeps the name in full - so a long table name is complete in the file name and shortened on the tab inside it.
→Dates and timestamps become genuine date cells, formatted yyyy-mm-dd and yyyy-mm-dd h:mm:ss, rather than strings that merely look like dates. Sorting and date arithmetic work on them with no conversion step first.
→A text column of digits stays text: a value like 01234 is written into a string cell, and Excel shows it as it was stored instead of dropping the zeros the way it does when the same data is opened from a CSV.

Reading SQLite3

→Declared types, primary keys, NOT NULL constraints and blobs all carry through.
→SQLite reports INTEGER PRIMARY KEY as nullable because it aliases the rowid; the conversion corrects that.
→SQLite type affinity is loose, so a NUMERIC column with no declared scale is given room for decimals rather than being rounded to whole numbers.

Writing XLSX

→One file per table. Booleans stay booleans and numbers stay numbers.
→Excel has no fixed-point type, so decimals become numbers — use a database target if exactness matters.

What you get

A ZIP containing <table>.xlsx. If anything about your data needed a judgement call, a _warnings.txt explains it.
