Notepad ++正则表达式在每一行中找到一个“，”并用“。”替换奇数“，”
[英]Notepad++ regular expression find a “,” and replace odd “,” with “.” in every row
问题描述
I ran into a mess recently with my data aquisition program which saves four datapoints separated by a comma(csv format) every couple of milliseconds. 
最近我的数据采集程序遇到了麻烦，它每隔几毫秒就会保存四个以逗号（csv格式）分隔的数据点。 I used a PC (NL region) where the decimal point is a "," for data acquisition. 我使用PC（NL区域），其中小数点是“，”用于数据采集。
Now when i try to import my csv file to matlab/excel it gives me 8 columns (which should be 4) as all the decimals are also printed as "," 现在，当我尝试将我的csv文件导入matlab / excel时，它给了我8列（应该是4），因为所有小数也都打印为“，”
Is there a way to use regular expression in notepad++ (for eg) to find all "," in a row, and replace the odd ones to a "."? 有没有办法在记事本++中使用正则表达式（例如）连续查找所有“，”，并将奇数替换为“。”？
Thanks a lot for any help. 非常感谢您的帮助。 I have thousands of rows of data such that doing it manually will take ages. 我有数千行数据，因此手动操作需要很长时间。

要匹配所有奇怪的逗号，请使用前面的断言，声明偶数个逗号：
,(?=(([^,]*,){2})*[^,]*$)
