Load Excel data sheet to Oracle database

Question

I am looking for a free tool to load Excel data sheet into Oracle database. I tried oracle sql developer, but it keeps throwing NullPointerException. Any ideas?

Answer 1

If you're handy with perl, look at Spreadsheet::ParseExcel.

Answer 2

Excel -> CSV -> Oracle

Save the Excel spreadsheet as file type 'CSV' (Comma-Separated Values).

Transfer the .csv file to the Oracle server.

Create the Oracle table, using the SQL CREATE TABLE statement to define the table's column lengths and types.

Use sqlload to load the .csv file into the Oracle table. Create a sqlload control file like this:

load data
infile theFile.csv
replace
into table theTable
fields terminated by ','
(x,y,z)

Invoke sqlload to read the .csv file into the new table, creating one row in the table for each line in the .csv file. This is done as a Unix command:

% sqlload userid=username/password control=<filename.ctl> log=<filename>.log

OR

If you just want a tool, use QuickLoad

Answer 3

Oracle Application Express, which comes free with Oracle, includes a "Load Spreadsheet Data" utility under:

Utilities > Data Load/Unload > Load > Load Spreadsheet Data

You need to save the spreadsheet as a CSV file first.

Answer 4

If this is a one time process you may just want to copy and paste the data into a Microsoft access table and do an append query to the oracle table that you have setup through your odbc manager.

Answer 5

Another way to do Excel -> CSV -> Oracle is using External Tables, first introduced in 9i. External tables let you query a flat file as if it's a table. Behind the scenes Oracle is still using SQL*Loader. There's a solid tutorial here:
