+- Convert a column string in Excel to a number. 
+  - :kr: 엑셀 컬럼 문자열을 숫자로 변환합니다.

 ## Example
 
 ```cpp
-unsigned int debug1 = excelColumnNumber::excelColumnStingToNumber("AB");
-std::string debug2 = excelColumnNumber::convertFromNumberToExcelColumn( debug1 );
-assert( debug2 == "AB" );
+    std::cout << " [1] ------------ " << std::endl ;
+
+    std::cout << "   0 : " << QXlsx::columnNumberToString( 0 ) << std::endl ;
+    std::cout << "   1 : " << QXlsx::columnNumberToString( 1 ) << std::endl ;
+    std::cout << "   2 : " << QXlsx::columnNumberToString( 2 ) << std::endl ;
+    std::cout << " 100 : " << QXlsx::columnNumberToString( 100 ) << std::endl ;
+    std::cout << " UINT_MAX : " << QXlsx::columnNumberToString( UINT_MAX ) << std::endl ;
+
+    std::cout << " [2] ------------ " << std::endl ;
+
+    std::cout << " a : " << QXlsx::alphabetToNumber('a') << std::endl ;
+    std::cout << " z : " << QXlsx::alphabetToNumber('z') << std::endl ;
+    std::cout << " A : " << QXlsx::alphabetToNumber('A') << std::endl ;
+    std::cout << " Z : " << QXlsx::alphabetToNumber('Z') << std::endl ;
+    std::cout << " 5 : " << QXlsx::alphabetToNumber('5') << std::endl ;
+
+    std::cout << " [3] ------------ " << std::endl ;
+
+    std::string columnString = "AB";
+    unsigned int debug1 = QXlsx::columnStringToNumber( columnString );
+    std::string debug2 = QXlsx::columnNumberToString( debug1 );
+    std::cout << debug1 << "   " << debug2 << std::endl;
+    assert( debug2 == columnString );
+```
+
+- Output : 
+
+```
+ [1] ------------ 
+   0 : 
+   1 : A
+   2 : B
+ 100 : CV
+ UINT_MAX : MWLQKWU
+ [2] ------------ 
+ a : 1
+ z : 26
+ A : 1
+ Z : 26
+ 5 : 0
+ [3] ------------ 
+28   AB
