how do I exports all sheets to single pdf files with sheet name?

I have a calc document with 100 sheets. I want to generate 100 pdf with the name of each sheet, not one big pdf…
I managed to do it in Excel but not in Libre Office…

I managed to do it in Excel

How? Trying to export to PDF from Excel 2016, I only see an option to export to a single file (maybe limiting to active sheet or selection), not to a series of files…

Also: A sheetname may not be qualified as a filename.
If the most simple case concerning the names and the target folder (same as origional .ods) as well as the pdf options is assured, a macro for the task shouldn’t be too complicated. Study the famous texts by Andrew Pitonyak. The appropriate export filter should be calc_pdf_Export.

You can do it by your own macro.

It is not very difficult

Sub ExportAllSheetsToPDF
Rem Export options. Now they are minimal. To adjust the PDF format accurately, 
Rem see
Dim ExportArgs(1) as new
Dim dataRange(0) as new

Dim oSheets As Variant, oSheet As Variant, oCursor As Variant
Dim sPath As String, sFileName As String
Dim i As Long
	sFileName = ThisComponent.URL
	If sFileName = "" Then Exit Sub	' This spreadsheet wasn't saved, so it hasn't path and name '
Rem Folder to store PDF - same as source file
	sPath = ConvertFromURL(DirectoryNameoutofPath(sFileName,"/"))
	If Right(sPath,1) <> GetPathSeparator() Then sPath = sPath + GetPathSeparator()	
	ExportArgs(0).Name = "FilterName"
	ExportArgs(0).Value = "calc_pdf_Export"
	ExportArgs(1).Name = "FilterData"
	dataRange(0).Name = "Selection"
	oSheets = ThisComponent.getSheets()
	For i = 0 To oSheets.getCount()-1
		oSheet = oSheets.getByIndex(i)
		If oSheet.isVisible Then ' Skip hidden sheets '
Rem Export range with data only (skip first empty columns and rows)
			oCursor = oSheet.createCursor()
Rem Set range with data as param of filter export
			dataRange(0).Value = oCursor
			ExportArgs(1).Value = dataRange()
Rem Create filename by sheet name
			sFileName = sPath + oSheet.getName()+".pdf"
Rem Export
	Next i
End Sub
