Excel Truncating Length Ssis Chart

  1. You can copy and paste a column of 16 digit numbers into excel like this: Open a new excel document. Leave it blank then click FILE / SAVE AS. From the type box, select 'text (tab delimited file)' option. Format the column where you want to paste the 16 digit numbers as 'text'.
  2. Which version of SSIS and Excel are you using? Which provider are you using? I just tested it with SSIS 2016, Excel 2016 and the ACE OLEDB 12.0 provider. I could read very large numbers just fine, even though they were formatted as scientific notation. What format do the cells have in Excel?

SymptomsWhen you retrieve the external data from an Excel Workbook within an SSIS package, fields that have more than 255 characters will be truncated to 255 characters. In case of SSIS, theexternal columns of the Excel Source component will be limited to a maximum length of 255 characters if the first 8 rows of the Excel Workbook contain fields with a length less or equal than 255 characters. CauseYour data may be truncated to 255 characters if the first 8 rows in the Excel Workbook for the field(s) being truncated contain 255 or fewer characters.

The Microsoft Excel ODBC driver will, by default,scan the first 8 rows of your data to determine the type of data in each column. If any of the rows after the first 8 rows of the Excel Workbook contain field(s) having lengths greater than 255 characters these will get truncated.Figure 1In the example represented in Figure 1 the Description field has 255 characters or fewer in the first 8 rows. As the Microsoft Excel ODBC driver, by default, scans only the first 8 rows of the Excel Workbook willdefine the metadata for the Description External Column to be of type DTWSTR having a length of 255 characters. However in the 9th row the Description value has a length of 1000 characters and it willbe truncated. The Excel Source component will not fail but it will truncate the value of the Description field in the 9th row to 255 characters. ResolutionTo change the number of rows that the Excel ODBC driver scans to determine what type of data you have in your table, change the setting of the TypeGuessRows DWORD value.
