TextExporter is a plug-in for InDesign CS, CS2, CS3 or CS4. It allows you to export all the text from an InDesign document concatenated into a single RTF file, while following a natural reading order. Text files and InDesign Tagged Text are also supported.
The latest version adds support for properly exporting the bullets or numbers that are created by using bulleted and numbered paragraph styles in InDesign – normally, these bullets vanish from the resulting RTF file when exported.
