When exporting a report to excel all cells that have a conditional fill formula are highlighted regardless if they should be or not. In the images below you will see the difference in the design view vs the excel export. Is this a limitation in Ignition?
If there is any more information I’d be happy to provide it. My customer wants excel reports in order to manipulate them, but they also like the ease of seeing the problem cells highlighted.
Looks like a potential bug so you may want to contact Support directly. If you need a quick workaround, this thread may provide some inspiration.
