我已经从一个共享点列表网站上下载了一个数据表到一个excel文件中，并过滤了关键字“合同”，这使我的搜索结果从1000行缩小到大约180行。
我的任务是确定日期X和Y之间的承包商数量。
我通常使用的过滤器是：
Employment Type = Contract
Contract Start Date >= 10/01/2017
contract End Date <= 05/31/2018
我遇到的问题是所有这些数据都包含在1个单元格中，“合同”的拼写有两种变体（合同和联系方式）。所以我也必须考虑这一点。
这是其中一个单元格中的一小段：
"Position":"Account Services Agent","Manager Name":"xxxx","Manager Phone":"43524325","Employment Type":"Contract","Contact Start Date":"01/08/2018","Contact End Date":"03/30/2018","Beeline Request ID number":"67160"},{"ID":"1111","Name":"xxxx ","Position":"Account Services Agent","Manager Name":"xxxx ","Manager Phone":"4444444","Employment Type":"Contract","Contact Start Date":"01/08/2018","Contact End Date":"03/30/2018","Beeline Request ID number":"67160"},{"ID":"333333","Name":"xxxx ","Position":"Account Services Agent","Manager Name":"xxxxx ","Manager Phone":"44444","Employment Type":"Contract","Contact Start Date":"01/08/2018","Contact End Date":"03/30/2018"
我需要以某种方式确定有多少符合我的日期范围标准的承包商
任何想法/解决方案将不胜感激。
