Convert IIF to SQL Online

Paste an IIF table below, edit it if you need to, and get SQL back. The conversion runs in your browser, so nothing is uploaded, there is no size limit and there is no signup.

What IIF is

IIF is QuickBooks Desktop's import and export format: tab-separated, with several tables interleaved in one file. A line starting with an exclamation mark defines the columns for a record type, and the data lines that follow begin with that type's keyword.

QuickBooks Desktop users, and the bookkeepers who have to move data into and out of it.

What SQL is

SQL here means the statements that move a table into a database: INSERT INTO with a VALUES list, and optionally the CREATE TABLE that defines the columns.

Anyone seeding a database, moving a spreadsheet into an application, or writing a migration.

What changes when you convert IIF to SQL

The largest table in the file is used, which is almost always the transactions. A typical export holds TRNS rows for the transactions and SPL rows for their split lines; those are two tables, not one, and combining them would produce a column layout that fits neither.

String values are escaped by doubling any single quote. Statements are written in batches so a large table does not become one statement megabytes long, which many clients refuse. Ask for CREATE TABLE as well and column types are inferred: a column stays INT until a value does not fit, then widens to DECIMAL, then to VARCHAR.

What carries over from IIF to SQL

SQL can express everything IIF holds about a table, so this conversion is about shape rather than loss.

SQL wants a type for each column, and IIF does not record one, so each column is typed from what its values look like. A column of digits that should stay text - a zip code, a phone number, a leading-zero id - is the usual thing to check afterwards.

A worked example

Three rows of staff data, with an identifier that has a leading zero, a value containing a comma, a value containing quotes and one blank cell. Those are the four places formats disagree, so they are the four places to look.

Questions

How do I convert IIF to SQL?

Paste your IIF into the box above or drop the file onto it. Check the table in the grid, then copy or download the SQL from the output panel. It takes one step and the data never leaves your browser.

Why does my IIF file have two sets of headers?

Because it holds two tables. TRNS lines are transactions and SPL lines are the splits belonging to them, and each has its own column definition. They are separate exports that happen to share a file.

Are the generated INSERT statements safe to run?

Quotes in your data are escaped, so the statements are syntactically correct. They are not parameterised, which is fine for a one-off import you are running yourself and not fine as a pattern for application code that takes user input.

Is there a limit on file size?

No. The work happens on your own machine, so the limit is your machine's memory rather than an upload cap. A file with tens of thousands of rows converts in a second or two.

Is my data uploaded anywhere?

No. The parsing and generating are done by JavaScript running on this page. You can watch the network tab while you convert and see that nothing is sent.
