Java CSV Parser

String.split(regular express)

But... 有規則就會有例外

資料中含有分隔字元 ( 貨幣 ...)

xxxxxx, xxxxxx, "aaa,bbb,c "

分行字元 ?

OpenCSV ( http://opencsv.sourceforge.net ) )

Read a CSV file new CSVReader(FileReader, <quote>,<sp>,<skip line>) String line = CSVReader.readNext(); List<String> list = CSVReader.readAll();

Read a CSV file

new CSVReader(FileReader, <quote>,<sp>,<skip line>)

String line = CSVReader.readNext();

List<String> list = CSVReader.readAll();

List<YourObject> list = CSVToBean.parse( ColumnPositionMappingStrategy, Reader );

List<YourObject> list = CSVToBean.parse( ColumnPositionMappingStrategy, Reader );

Write a CSV file: CSVWriter writer = new CSVWriter( new FileWriter(&quot;yourfile.csv&quot;), ' '); String[] entries = {&quot; first &quot;, &quot; second &quot;, &quot;third &quot;} writer.writeNext(entries); writer.close();

Excel TimeStamp Excel PC 上序列值以 1900-1-1 為 1 ，每過一天加 1 Excel Mac 上序列值以 1904-1-1 為 1 用 Mac 打開 PC 版本， Copy/Paste 不會出錯，自己打就會出錯 Unix 以 1970-1-1 00:00:00 UTC ，每一秒加 1

Excel Bug: From Lotus 1-2-3 當年為了市佔率 1900 並不是閏年，但被當成閏年處理 （ 1900-1-1 ~ 1900-3-1, 會出現 1900-2-29 ）
