@albert, You need to becareful when doing the divide, because there is no
ZERO. (Z -> AA not Z->A0).
here is the code:
public static String ExcelMapIntToStr(int n)
{
StringBuilder sb = new StringBuilder();
while(n>0)
{
sb.append((char)(('A' - 1) + (n-1)%26 + 1));
n = (n-1)/26;
}
return sb.reverse().toString();
}
public static int ExcelMapStrToInt(String str)
{
int val = 0;
int base = 1;
for(int i = str.length() - 1; i>=0; i--)
{
val += (str.charAt(i) - ('A' - 1))*base;
base *= 26;
}
return val;
}
