MDL ISIS for Excel 2.0

MDL ISIS for Excel is a legacy add-in that brings chemistry-aware capabilities to Microsoft Excel. Part of the MDL ISIS suite, it lets scientists work with chemical structures and reactions directly in spreadsheets, combining familiar Excel workflows with structure handling, search, and basic property calculations.

Key features:

• Embed and edit chemical structures in cells, with structure objects that resize, copy/paste, and print cleanly.
• Perform exact, substructure, and similarity searches across spreadsheet data.
• Calculate common properties such as molecular weight and atom counts; extendable via compatible plugins.
• Import and export standard chemistry formats (e.g., SDF, MOL, RXN) for smooth data exchange.
• Support reaction data tables and stoichiometry tracking alongside numeric and text fields.
• Integrate with other components of the ISIS ecosystem (for example, ISIS/Draw and, where licensed, ISIS/Base).

Typical uses:

• Building SAR tables that link structures to assay results.
• Curating and QC’ing compound libraries in spreadsheet form.
• Preparing SDF exports for registration systems or downstream analysis.
• Filtering large datasets by substructures or scaffold patterns.

Notes:

• This is a classic tool widely used in the late 1990s and 2000s; it was designed for older versions of Windows and Excel, so compatibility with modern environments may be limited.
• Availability and support status may vary; consider contemporary chemistry add-ins if you require current OS and Office support.
