Description
An XLSX file is an Excel spreadsheet created by Microsoft Excel or another spreadsheet program, such as OpenOffice Calc or Apple Numbers. It stores data in worksheets, which contain cells arranged in a grid of rows and columns, and may also contain charts, mathematical functions, styles, and formatting. XLSX files are commonly used to store financial data and to create simple or complex mathematical models.
ICML (Adobe InCopy Markup Language) is an XML-based file format used to exchange document content and formatting between Adobe InDesign and InCopy. It preserves text, styles, and layout information so that writers and editors using InCopy can work on content linked to an InDesign layout. It is commonly used in publishing workflows for collaborative editing of page layouts.
