Excel to IDF

Usage

For the other way around, I wrote a macro that will read in an excel table and export that to an IDF compatible object so that you can paste it in the IDF editor or in your .idf text file itself.

I've personally added this macro to an Excel Add-In and added a button on a separate tab for easy access:

To use the macro, place your cursor in any of the cells of the table and launch it. It will try to find the EPlus class name in the cell that's 2 rows above the top-left corner of the table to prepopulate a dialog box asking you for the class name: either it's good and click OK, or it isn't or it didn't find it, type the name of the class. It'll then generate proper IDF objects that you can paste in IDF editor or paste directly in the .idf file. It'll ask you whether you want to save it as a file (and subsequently ask for a file name) or copy it to clipboard.

Example

Here's an example:

And Here's the output it produced for the example table:

Eplus:ObjectClass,
    Object 1,
    (1,1),
    (1,2),
    (1,3);

Eplus:ObjectClass,
    Object 2,
    (2,1),
    (2,2),
    (2,3);

Eplus:ObjectClass,
    Object 3,
    (3,1),
    (3,2),
    (3,3);

Add-In

I've set up a quick Excel Add-In with some instructions a couple more things in my github: Useful Excel Macros for Energy Modeling. It includes:

• Some shortcuts
• A macro to export an Excel table to an IDF format for import into IDF Editor or to paste in the idf file directly
• A macro to export an excel table to a JSON array of hash: useful when working with ruby and the OpenStudio bindings especially
• And obviously a readme file

Want just the macro?
