我的任务是在公司拥有的SPLA服务器上自动执行部分日志记录过程。我的任务是更新，存档和删除旧文件，然后转到生成报告，通过电子邮件发送给部门。这项任务应该在每周结束时运行。
我认为powershell将是完成此任务的最佳选择。这是我第一次使用PowerShell，所以我有点学习。
我的问题：
是否可以循环使用Excel工作表并使用此脚本删除未使用的行？
我的情况是，如果有两个空行 - ＆gt;删除一行并继续
我从日志中获取信息并将其拆分为CSV，然后将CSV转换为Excel格式化。

#---------------#--#--------------#
# -[/] <-Complete -[] <- Incomplete
# -[] Archive or delete CSV Files
# -[] Add a If/Else statement that checks if files are >7 days old
# -[] Compile a weekender report that indicates any SPLA programs changed to keep compliance
# -[] Filter for only SPLA files (Need a list)
# -[] Loop through CSV/Excel file and delete empty rows
以下代码贯穿整个程序：
for($i = 350 ; $i -ge 0 ; $i--) {
If ($SPLA1wksht.Cells.Item($i, 1).Text-eq "") {
$Range = $SPLA1wksht.Cells.Item($i, 1).EntireRow
[void]$Range.Delete()
echo $i
}
If ($SPLA1wksht.Cells.Item($i, 2).Text-eq "") {
$Range = $SPLA1wksht.Cells.Item($i, 2).EntireRow
[void]$Range.Delete()
echo $i
}
If($i -eq 2){ break;}
}
答案 0 :(得分：0)
这应该是相对简单的
$file = C:\path\to\file.csv
$csv = Import-Csv $file
foreach($row in $csv) {
# logic to delete row
# $csv is an array, so you can could make the row = null to delete it
}
# spit out updated excel sheet
