How your data is typed in CSV
Generated from the converter's own CSV type mapping — this is what it actually emits, not an example.
| Your data | CSV type |
|---|---|
| Whole number | text (CSV has no types) |
| Decimal (money) | text (CSV has no types) |
| Floating point | text (CSV has no types) |
| True / false | text (CSV has no types) |
| Date | text (CSV has no types) |
| Date and time | text (CSV has no types) |
| Short text | text (CSV has no types) |
| Long text | text (CSV has no types) |
| Binary data | text (CSV has no types) |
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.
The shape of the CSV files you get
CSV is where the type information stops, so what is left to describe is the file itself: how a row is terminated, which fields are quoted, and how a value that used to have a type is spelled out as characters.
- →Rows end with a carriage return and a line feed, the RFC 4180 ending, while a newline inside a quoted field stays the single character it always was. The encoding is UTF-8 with no byte-order mark in front of it.
- →Quotes go on only where they are needed - a field holding a comma, a double quote or a newline - and a quote inside a field is doubled rather than escaped with a backslash. Every other field is written bare.
- →Decimal values are written digit for digit and never through a floating-point number, so a money column that was exact in the source is still exact in the file. Booleans are written lower case, as true and false, which is the spelling this converter's own reader takes back as a boolean.
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 CSV
- →One file per table, with a header row.
- →NULL is written as an empty field, never the word "None".
- →Binary data is written as hex, which is reversible.
What you get
A ZIP containing <table>.csv. If anything about your data needed a judgement call, a _warnings.txt explains it.
Questions
- Is converting SQLite3 to CSV 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 CSV?
- Yes — that is the point. Whole numbers, decimals, dates and booleans are mapped to real CSV 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.
