将log日志,复制到单独一行 B列（可能一行很长，所以将整合后的放在A列）

使用公式可以筛选出 包含某些字符串的行 为true，将这些行直接删除

=IF(COUNT(FIND("MediaMuxterThreadRussia",B2,1))>0,"包含","不包含")

=OR(ISNUMBER(SEARCH("MediaMuxterThreadRussia", B2)), ISNUMBER(SEARCH("dispatchKeyEvent:", B2)))
=OR(ISNUMBER(SEARCH("keyCode", B2)), ISNUMBER(SEARCH("D/y.e.a.a.i0: Read data:", B2)))
=OR(ISNUMBER(SEARCH("D/y.e.a.a.z:", B2)), ISNUMBER(SEARCH("/sys/class/leds/record", B2)))
=OR(ISNUMBER(SEARCH("Record Data Denoise:", B2)), ISNUMBER(SEARCH("Record Data Raw:", B2)))
=OR(ISNUMBER(SEARCH("send voice data:320", B2)), ISNUMBER(SEARCH("_MYT: OTG status:0", B2)))
=OR(ISNUMBER(SEARCH("operationComplete: 消息发送成功! cmd= 118, data length= 1298", B2)), ISNUMBER(SEARCH("I/SystemUtils_MYT: execCmd_2: cmd = echo", B2)))
=OR(ISNUMBER(SEARCH("sendAudioData: totalArray lenth= 1288", B2)), ISNUMBER(SEARCH("I/NettyClient_MYT: sendAudioData: groupid= 12713, istemp= 0", B2)))
=OR(ISNUMBER(SEARCH(" onReceivedAudioEvent: audioData length = 1280", B2)), ISNUMBER(SEARCH("processResponse: groupIdList id= 12713", B2)))

使用公式可以将某些长字符串 变成 短字符串

=IF(ISNUMBER(SEARCH("发送对讲音频数据", B2)), LEFT(B2, 100), B2)=IF(ISNUMBER(SEARCH("queueReceivedAudioData", B2)), LEFT(B2, 130), B2)
