Hide Layers and Export

This script will identify folders across multiple InDesign files with included var values and turn them off before exporting.

How to use

• Create/export a new Extended Script file in VS Code
  • Identify what layers you want to hide and substitute them with the layerName variable in this block

try {  
	doNotPrintLayer = doc.layers.item(layerName);  
	if (doNotPrintLayer.isValid) {  
		originalVisibility = doNotPrintLayer.visible;  
		doNotPrintLayer.visible = false;  
	}  

• Drop script into InDesign User/Scripts Folder
• Create local folders for INDD files you want to run script on and where exported files can land.
• Run script
• You will be prompted to select INDD files to export and where to drop exported JPG files
