Created attachment 33006 [details] CellReference.java patch A few minor changes to CellReference: * Compare cellRefString.toUpperCase() with "#REF!" for CellReference(String) * Change private separateRefParts(String) to return a struct instead of a 3-element String array. The goal here was to make the code easier to read and more flexible if POI supports cell references external to the workbook, though I don't know if creating an object is more expensive (time or memory) than a String array. Do we have a good way to test this? * Update javadoc for separateRefParts
Thanks, patch committed in r1696430. (Even if the string[] is a smidgen faster, readability is important to, so seems worth it)
