i trying format different columns of excel sheet based on 2 conditions: if cell not contain letter "u" or letter "r" , if greater set number. for example, if have column of data, want 0.3 highlighted because greater set number of 0.00834 , not contain u or r. don't want 0.0071u highlighted or 0.0056j. any help? select cells/column(s) want conditional format applied (for example assume use column b:b ) check cell active - "white" cell in blue selection. (i assume it's b1 ) create new conditional format home -> conditional formatting -> new rule select "use formula determine cells format" enter following formula: =and(right(b1,1)<>"u",right(b1,1)<>"r",if(isnumber(b1),b1,value(left(b1,len(b1)-1)))>0.00834) make sure b1 active cell step 2. make sure not using $ fix row or column. note: formula assumes cells contain either proper numbers - or number , single letter @ end! set
