We have found 2 software records in our database eligible for .indb to .indd file format conversion.
Both .indb and .indd files come from InDesign, albeit from different versions. What many users are actually searching for, is how to turn multiple old .indb files into a single. indd file. In the past you could have found scripts on Internet that could be used to automate the otherwise manual process. If you import .indb files to InDesign you can access these from the Book panel. In any case, if you struggle with this or need additional help, it might be best to contact Adobe support or community.
