Gilbert Consulting offers custom Adobe InDesign and Illustrator scripts to solve workflow issues. They provide 38 free scripts designed to automate tasks and enhance functionality within these programs. These scripts cover a range of functions, from adding hyperlinks and page buttons to analyzing documents and exporting files in various formats. Many scripts address specific formatting needs like table styles, accessibility checks, and image conversions. The scripts are frequently updated, and several are accompanied by blog posts or videos offering further instruction and context.
