Move Oracle data into Microsoft Excel

Microsoft Excel is perhaps the most effective solution for creating reports from databases because of the following features:

  • easy-to-use intuitive interface
  • formulas
  • data visualization (graphics and charts)

Previously, formats of MS Excel had limit on max rows count 65535 and this fact restricted it from making use of it a front-end for large databases. Nevertheless, beginning from Excel 2007, this restriction has been increased up to 1048576 rows that permits the conversion of medium size database tables into MS Excel worksheets.

So, in what way can you export Oracle data into MS Excel format? You’ll find multiple techniques to achieve this process, let’s examine few of them.

  1. Use Microsoft Data Access components.
  • create new workbook in Microsoft Excel
  • select “Data > External Data > From Other Resources > Data Connection Wizard” menu item
  • in the appeared dialog window select “Microsoft Data Access – OLE DB Provider for Oracle” option
  • push “Next” button
  • enter server, username and password
  1. Export through comma separate values (CSV) file.

It is quite easy to generate csv file with necessary Oracle data using SPOOL directive:

set pagesize 10000

set feedback off

set heading off

select to_char(id)||’,’||rtrim(name)||’,’||rtrim(phone)||’,’||to_char(hire_date,’dd-mon-yyyy’) from emp;

spool off

set echo on

set heading on

set feedback on

As soon as you are done running these statements from SQL*Plus, it will develop a employee.csv file with ‘id’, ‘name’, ‘phone’, ‘hire_date’ columns. The completed csv file can be swiftly imported into MS Excel spreadsheet.
