Value Meaning
0 No updates
1 Updates external but not remote references
2 Updates remote but not external references
3 Updates both remote and external references

ReadOnly
If True, the workbook is opened in read-only mode.
Format
If Microsoft Excel is opening a text file, this argument
specifies the delimiter character, as shown in the following
table. If this argument is omitted, the current delimiter
is used.
Value Delimiter
1 Tabs
2 Commas
3 Spaces
4 Semicolons

how to update links. Otherwise, this argument is one of
the values shown in the following table.
Value Meaning
0 No updates
1 Updates external but not remote references
2 Updates remote but not external references
3 Updates both remote and external references
If Microsoft Excel is opening a file in the WKS, WK1, or

Excel generates charts from the graphs attached to the file.
If the argument is 0, no charts are created.
ReadOnly
If True, the workbook is opened in read-only mode.
Format
If Microsoft Excel is opening a text file, this argument
specifies the delimiter character, as shown in the following
table. If this argument is omitted, the current delimiter
is used.
Value Delimiter
1 Tabs
2 Commas
3 Spaces
4 Semicolons
5 Nothing
6 Custom character, see the delimiter argument.
