How to get formated text from Filemaker to Indesign

1. Create a document with all style used.
2. Export the text as InDesign tagged style.
3. Look into the InDesign markers before and after each style.
4. When you export content from a DB, not only export the field’s content, add the style markers from step 3 before and after the style where it should be used. You need only the name, not the whole definition as it will take it from the host document where it is complete defined.
5. Place this exported txt file.

Here are some options, not in any particular order:

• If you are still using the database, you can create fields that combine the original field with InDesign text tags. For example, the FirstNameExport would concatenate the FirstName field and the ID tagged text code.
• You can basically do the same thing by exporting to Excel and adding the tagged text there (again with the concate function).
• You could convert the tab-delimited output to a Word file and use a next-style format cycle if the data is repetitive.
• You can use a plugin like InData for more control over the formatting (and not use tagged code). 
• If you still use the database, you can use a plugin like InCatalog that can link to the database via ODBC. 

If you have, or can lay a hand on a copy of FileMaker Pro, I'd suggest a export from FMPx through DBF dBASE flatfile to Excel XLS workflow.

Technically, you could patch your way from a dBASE flatfile, or you could use a comma-delimited CSV file, but transferring it to Excel gives you much better tools to fix discrepancies within the database structure. And you can count on the flatfile needing some exra loving to make things right before you pour the end results into InDesign.

Hope this helps,

Not really too sure on this one but found this thread. Might help
