Request for adding an API support for Conditional Formatting.
GemBox.Spreadsheet supports Conditional Formatting only through the preservation in XLSX files.
Which means that any previous formatting we made on our XLSX file will be preserved when we load this file with GemBox.Spreadsheet and save it back to an XLSX format, but they are not directly supported by GemBox.Spreadsheet API.
The following link is a demonstration sample of preserving Conditional Formatting when reading from XLSX file and writing to XLSX file:
More informations about GemBox.Spreadsheet's preservation can be found on the following link:
