Perhaps I spoke a little too soon. I am able to export the tables to a SQLite database, but it doesn't like the ID fields at all.

I'm using this:

foreach ($table in $TransmittalsDataSet.Tables)
{
New-XLSXWorkbook -InputTables $table -OutputFileName D:\temp\DM\TransmittalsExportTest.xlsx
# Copy the table
$table_copy = $table.Copy()
# Export the table to SQLite
Export-DataTableToSQLiteDB -OutputFolder d:\temp -SourceDataTable $table_copy -OutputFileName SqlLiteTest3.db -append #-InputTable $table_copy
}

And when it's done, the ID Fields look like this:

Have you run across this before? Is it because I am trying to output to SQLite, or am I forgetting some sort of transformation?

Thanks, Zachary. That's even easier.

Hey Matt, glad you got it working.
A simple solution is to just copy the whole data table. Something like this:

foreach ($table in $Dataset.Tables)
{
    $table_copy = $table.Copy()
    Do-Whatever -InputTable $table_copy
}

That will save you having to rebuild the tables and populate row by row.
Hope this helps.

It appears that the solution was to go away for a little while and then come back with a fresh mindset.

Upon returning I had a "Duh" moment and created a new datatable with the same columns as the source one, copied the rows into the new datatable and then I had one that didn't "already belong to a dataset".
