列挙、値、および拡張子をすべて 1 か所にまとめたリストを見つけるのは難しいため、ここでは私が行った方法を示します。注意が必要な部分は、列挙を機能させることです (コードを参照してください)。

一部の形式を保存できない理由がわかりません。しかし、それらは非常に一般的または有用なもののようには見えません。
また、xlOpenXMLAddIn 形式は非常に奇妙です。「.ods」の拡張子を報告しますが、それは実際に保存するものではありません。作成したファイルを削除する場合は、xlOpenXMLAddIn 形式でコードを 1 回だけ実行するように変更します。
import win32com
from os.path import splitext
from time import sleep
xl = win32com.client.gencache.EnsureDispatch( "Excel.Application")
app = xl.Application
app.Visible = 1
book = app.Workbooks.Add(); book.Activate()
constants = win32com.client.constants
formatName = 'xlOpenXMLAddIn'
formatNum = getattr( constants, formatName)
print 'test_file_format: %s > %s' % ( formatName, formatNum)
app.DisplayAlerts = False
try: book.SaveAs( r'C:\excel_file_formats\xlbook', formatNum)
except Exception: print 'could not save this format'
else:
wbname, wbext = splitext( book.Name)
print '"%s" > "%s"' % ( wbname, wbext)
あなたはこれを得る:
test_file_format: xlOpenXMLAddIn > 55
"Book1" > ""
作成されるファイルの名前は「xlbook.xlam」です。Excelのタイトルバーには「Book1 - Microsoft Excel」と表示されています。だから私はこれで何が起こっているのか分かりません。いずれにせよ、あまり有用な形式のようには見えません。
