Set db = DBEngine.OpenDatabase(vbNullString, False, False, "Excel 12.0 Xml HDR=YES IMEX=2 ACCDB=YES DATABASE=C:\Links\Products.xlsx") Additionally, we can “query” an arbitrary block in the sheet using cell address. If the Excel spreadsheet contains a named range, the named range will be reported as a “ Tabledef” as well. However, worksheets aren’t the only thing that can be a “ Tabledef“. In the previous sample, you saw that a sheet represented a “ DAO.TableDef“. Therefore a minimum working connection string can be:Įxcel 8.0 DATABASE=C:\Links\Products.xls Specifying sheet or range in connection string Note that the DATABASE is the only mandatory parameter in addition to the data type source keyword. The parameter should contain a fully qualified path, including the workbook’s name.

If anyone can share what effect this parameter, post in comment and I’ll update the blog. However, omitting it or setting it to NO seems to do nothing. ACCDB parameter: Indicates that Access is using ACCDB file format?īy default, this is always set ACCDB=YES in an accdb file format. That may cause an error in reading when we read a row that contains data that does not match the expected data type. Otherwise, match the column to the best data type.Ģ: Always match the column to a certain data type based on the sample. This governs how the column data types should be defined, based on the content:ġ: If the column contain different data types, treat it as a string. All column names will be named “FN” where “N” is a number starting with 1 IMEX parameter: Import/Export Behavior NO: The first row is not treated differently and is just a data. YES: The first row is the header and should become the column names for the “table”/”recordset” Here are the list of parameters: HDR parameter: Header row Excel connection string parametersĮven though we have 3 different data source “types”: This is a best-effort to cover some of the gaps and discuss the ramifications of parameters. There’s a dearth of documentation on the Excel connection string parameters. Because they do not use ODBC drivers, their connection string will be formatted quite differently from what you might be accustomed to seeing for an ODBC connection string. In the previous article, I discussed how we can treat Excel and text files as if they were a database using DAO, and how we can open them without linking.
