Microsoft recommends that you install the 32-bit version of Office 2010, even on 64-bit machines, since many of the common Office Add-ins did not run in the 64-bit Office environment. Formats include Access, CSV, delimited, DBase and Excelįor developing on a general-purpose 64-bit desktop computer, you’re likely to hit a very silly Microsoft muddle.

These drivers enable you to access a range of data files via SQL as if they were a relational database. This includes the more popular OLEDB drivers which run well in PowerShell too. XML), web-based data or spreadsheetĬurrently, the state of the art in ODBC for Access and Excel is the Microsoft Access Database Engine 2010 Redistributable which can be downloaded here. ODBC was conceived as a way of making it as easy to connect to a particular datasource such a relational database, text file, data document (e.g. When you have a large number of big spreadsheets to insert as a chore, then speed matters.
I also prefer to use ODBC and the sequential data reader to read data from Excel, or any other ODBC source, because it is fast and I like to use the bulk copy library to insert ODBC ‘reader’ data into a SQL Server table because it is extremely fast, so we’ll use that. If, for example, you only need the total, count, and variance of a day’s readings, then why on earth would you want to import more than those aggregated figures? Even if you do, these aggregations, performed on the original data, can be used as a ‘reconciliation’ check that you’ve gulped all the data into their final destination without error. This means that you need pull far less data into SQL because you can do a lot of selection and pre-processing before the data gets anywhere near SQL server.
There are some features missing, of course, but you can do joins between tables, filter rows to taste, do aggregations and some string manipulations. Worksheets, or areas within worksheets, become tables. If you use the ODBC driver, then your Excel workbook becomes a little SQL-based relational database. It is a Once and Future technology, developed before its time, but now showing its value for processing large volumes of data, despite its quirks, poor documentation and lackluster support. I always feel slightly awkward in talking about ODBC. This article will aim to show how this is done. It is possible to do a lot of filtering and aggregation of data before it ever gets to SQL Server, since you can turn an existing Excel Workbook into a poor-man’s relational database, or even create one. The most important thing, though, is that you can aggregate before you send the data. It is neater than SSIS too, and more versatile. It is quicker than automating Excel and you can do it without requiring a copy of Excel. The most important direction is from Excel to SQL Server, of course. It is reasonably easy to insert data from Excel into SQL Server, or the reverse, from any other ODBC database to any other, using PowerShell.
