Office Xml 2003转XLSX
一、使用到的依赖包
1、xelem-3.1.jar 下载地址：管网下载地址
2、poi-3.17.jar 下载地址：https://mvnrepository.com/artifact/org.apache.poi/poi
二、实现方法
1、Xml2003公式转XLSX公式算法
（1）Xml2003函数格式
SUM(R[-1]C+R[-7]C[-4])R代表当前行，C代表当前列，中括号中的数字代表相对于当前行的偏移量。比如当前操作的是第10行第三列6列，那么上面公式的含义就是第6列9行与第2列3行相加。转换成XLSX的公式就是
SUM(F9-B3)（2）代码实现
private final static String[] ExcelColIndexes = new String[]{
"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M",
"N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z",
"AA", "AB", "AC", "AD", "AE", "AF", "AG", "AH", "AI", "AJ", "AK", "AL", "AM",
"AN", "AO", "AP", "AQ", "AR", "AS", "AT", "AU", "AV", "AW", "AX", "AY", "AZ",
"BA", "BB", "BC", "BD", "BE", "BF", "BG", "BH", "BI", "BJ", "BK", "BL", "BM",
"BN", "BO", "BP", "BQ", "BR", "BS", "BT", "BU", "BV", "BW", "BX", "BY", "BZ"
};private static String convertFormula(String xmlFormula, int rowIndex, int colIndex) {
if (xmlFormula.equals("=SUM(RC[-2]-RC[-5])")) {
System.out.println();
}
StringBuilder formula = new StringBuilder(xmlFormula.replace("=", ""));
Pattern flaPattern = Pattern.compile("R(\\[[-]?\\d+\\])?C(\\[[-]?\\d+\\])?");
Pattern rowPattern = Pattern.compile("R(\\[[-]?\\d+\\])?");
Pattern colPattern = Pattern.compile("C(\\[[-]?\\d+\\])?");
Pattern numberPattern = Pattern.compile("[-]?\\d+");
Matcher flaMatcher = flaPattern.matcher(xmlFormula);
while (flaMatcher.find()) {
String subFla = "";
String content = flaMatcher.group();
Matcher colMatcher = colPattern.matcher(content);
if (colMatcher.find()) {
String colFla = colMatcher.group();
Matcher numberMatcher = numberPattern.matcher(colFla);
if (numberMatcher.find()) {
int num = Integer.parseInt(numberMatcher.group());
subFla = ExcelColIndexes[colIndex + num];
} else {
subFla = ExcelColIndexes[colIndex];
}
}
Matcher rowMatcher = rowPattern.matcher(content);
if (rowMatcher.find()) {
String rowFla = rowMatcher.group();
Matcher numberMatcher = numberPattern.matcher(rowFla);
if (numberMatcher.find()) {
int num = Integer.parseInt(numberMatcher.group());
subFla += rowIndex + 1 + num;
} else {
subFla += rowIndex + 1;
}
}
int start = formula.indexOf(content);
int end = start + content.length();
formula.replace(start, end, subFla);
}
return formula.toString();
}2、XML2003十六进制颜色向POI颜色转换
private static byte[] convertColorHexToByteArray(String colorStr) {
colorStr = colorStr.replace("#", "");
if (colorStr.length() != 6 && colorStr.length() != 8) {
throw new IllegalArgumentException("Must be of the form 112233 or FFEEDDCC");
} else {
byte[] rgb = new byte[colorStr.length() / 2];
for (int i = 0; i < rgb.length; ++i) {
String part = colorStr.substring(i * 2, (i + 1) * 2);
rgb[i] = (byte) Integer.parseInt(part, 16);
}
return rgb;
}
