I'm experiencing an error when trying to add a conditional formula that checks if the value is an Alphabetic character. Below is a snippet demonstrating this issue:
IConditionalFormats condition = sheet.Range["A1:A20"].ConditionalFormats;
IConditionalFormat condition1 = condition.AddCondition();
condition1.FormatType = ExcelCFType.CellValue;
condition1.Operator = ExcelComparisonOperator.Equal;
condition1.FirstFormula = "\'r\'"; // ERROR HERE
condition1.FontColor = ExcelKnownColors.Red;
condition1.Color = ExcelKnownColors.Red;
The code will compile fine, however when ran the following unhandled exception is thrown:
Syncfusion.XlsIO.Implementation.Exceptions.ParseException was unhandled
Message="r is not valid named range"
Source="Syncfusion.XlsIO.Base"

InnerException:
I attempted a number of variants for escaping the alphabetic character however nothing was successful.
Attached is a sample solution which demonstrates the issue. A support incident was opened for this (Incident #62049).
