Powershell 读取 Excel 中的一个选项卡并导出为 CSV

Question

I want to read a hidden tab in excel file and copy that tab and export it to csv.

I did this command, but it only output the meta data of that tab

$file = Get-ChildItem $sp | Where-object {$_.Name -match $patten} | sort LastWriteTime -Descending | select -first 1    
$wb = $excel.Workbooks.open($file.Name)    
$wb.Sheets.Item(4) | Export-Csv -Path "c:\Users\path\test.csv"

how should i get the actually content in that Tab (index No.4) and save as test.csv ?

Answer 1

Well you were close. This should do it.

$ws = $wb.Sheets.Item(4)
$ws.SaveAs("c:\Users\path\test.csv", 6)

Make sure, the path exists.

Answer 2

I would try to make the spreadsheet visible first.

use some code similar to this:

ws.sheet_state = 'visible'

This is a guess!
