• Select the column Matr.Nummer, use Format > Cells...

• Select in the box Category the item Number
• Down in the Format-Code box write: 00--000--000
• Hit okay (nothing will change yet)

• This column still selected use Edit > Find & Replace...

• In Search For give the two characters "^." and in replace with give just an ampersand "&".

• Then make sure the options "Current Selection Only" and "Regular Expression" are selected and hit "Replace all"
• Now the Numbers shut be formatted okay.
• Now in a unused column on the row as the first student paste there the formula:
  • =CONCATENATE("\exam{";B2;"}{";TEXT(C2,"00--000--000");"}{";D2,"}{";E2;"}{}")
• Change the cell references according to your data!
• Hit Enter, select this cell and drag the lower right corner downwards so that every students line gets its copy of that formula.
• Save the file.
• Select the Column with the formulas and copy it.
