WordsFlow solves the biggest headache in InDesign production: automatically merging changes in placed text or spreadsheet files into already-edited InDesign stories. It spares you the pain, frustration and errors of manually merging in changes from the external document. What's more, it works entirely invisibly, with no user interface beyond the normal link handling you're already used to for graphics.
Adds support for exporting (and later updating) page reference-style index markers to Word files.
Works around a bug in InDesign’s Excel import filter that causes a Relink to fail if the Cell Range or Sheet associated with the current link isn’t valid for the file to which the table is being relinked. This fix allows Relink to both update the table (and retain its changes) and alter the link’s Import Options (select Show Import Options in the Relink dialog and then select the new sheet and/or cell range).
Fixes a rare situation that could prevent link updates from working.
Fixes a problem where updating an Excel link using a non-Pro license could cause InDesign to shut down.
