SSIS does not implicitly convert data types. As a result, you may have to use Derived Column or Data Conversion transformations to convert Excel data explicitly before loading it into a destination other than Excel, or to convert data from a source other than Excel before loading it into an Excel destination. Conversion between Unicode Excel string columns and non-Unicode string columns with specific codepage. If you're using the Import and Export Wizard, and your data requires some of these conversions, the wizard configures the necessary conversions for you.
As a result, even when you want to use an SSIS package, it may be useful to create the initial package by using the Import and Export Wizard. Let the wizard create and configure connection managers, sources, transformations, and destinations for you. When you specify a worksheet or a named range as the source, the driver reads the contiguous block of cells starting with the first non-empty cell in the upper-left corner of the worksheet or range.
As a result, your data doesn't have to start in row 1, but you can't have empty rows in the source data. For example, you can't have an empty row between the column headers and the data rows, or a title followed by empty rows at the top of the worksheet.
If there are empty rows above your data, you can't query the data as a worksheet. In Excel, you have to select your range of data and assign a name to the range, and then query the named range instead of the worksheet.
The Excel driver reads a certain number of rows by default, eight rows in the specified source to guess at the data type of each column.
When a column appears to contain mixed data types, especially numeric data mixed with text data, the driver decides in favor of the majority data type, and returns null values for cells that contain data of the other type.
In a tie, the numeric type wins. Most cell formatting options in the Excel worksheet do not seem to affect this data type determination. You can modify this behavior of the Excel driver by specifying Import Mode to import all values as text. When the driver determines that an Excel column contains text data, the driver selects the data type string or memo based on the longest value that it samples.
If the driver does not discover any values longer than characters in the rows that it samples, it treats the column as a character string column instead of a memo column. Therefore, values longer than characters may be truncated. Make sure that the memo column in at least one of the sampled rows contains a value longer than characters. Increase the number of rows sampled by the driver to include such a row. You can increase the number of rows sampled by increasing the value of TypeGuessRows under the following registry key:.
Create an Excel Connection Manager with the path and file name of the new Excel file that you want to create. On the Choose a Destination page, select Browse. In the Open dialog box, navigate to the folder where you want the new Excel file to be created, provide a name for the new file, and then select Open.
When you specify a range as the destination, an error occurs if the range has fewer columns than the source data. However, if the range that you specify has fewer rows than the source data, the wizard continues writing rows without error and extends the range definition to match the new number of rows.
Before you can successfully save strings longer than characters to an Excel column, the driver must recognize the data type of the destination column as memo and not string.
