Get column name and data type from closed workbook
 

Good day Group,

Found the code below from this group that helps me to retrieve the Sheet
names from
a closed Workbook. Is it possible to get the name of the columns (fields)
from
a Worksheet in a closed Workbook in the same way? Is it posssible to get
the format (data types) of each column? As new to this I´am grateful for
some
hints.

The column headers are in Row 1 of each table. Using ADO method
indexing starts at zero so you are lokking at row 0.

For Each tbl In cat.Tables
szTableName = tbl.Name
''' Worksheet names always end in the "$" character.
If Right$(szTableName, 1) = "$" Then
Sheets("data").Cells(lRow, "B").Value = _
Left$(szTableName, Len(szTableName) - 1)
Set HeaderRow = tbl.Rows(0)
ColCount = 3
for each col in HeaderRow.Cells
Sheets("data").Cells(lRow, ColCount).Value = col
ColCount = ColCount + 1
next col
lRow = lRow + 1
End If
Next tbl

Was it my code or Tim's website that solved your problem?
