You can use sql loader, but if you want a more robust solution (especially if the data will be modified directly in the spreadsheet) then look into external tables in Oracle. You can build a database table directly from the spreadsheet, the code looks like this:

CREATE TABLE YOUR_SCHEMA.YOUR_TABLE
(
  ACCT_NO                   VARCHAR2(15 BYTE),
  PRODUCT_TYPE              VARCHAR2(50 BYTE),
  ORGINATION_DATE           VARCHAR2(20 BYTE),
  MATURITY_DATE             VARCHAR2(20 BYTE),
  FIXED_PERIOD_START_DATE   VARCHAR2(30 BYTE),
  FIXED_PERIOD_END_DATE     VARCHAR2(30 BYTE),
  ORIGINAL_LOAN_AMOUNT      NUMBER,
  CURRENT_BALANCE           NUMBER
)
ORGANIZATION EXTERNAL
  (  TYPE ORACLE_LOADER
     DEFAULT DIRECTORY YOUR_DIRECTORY
     ACCESS PARAMETERS 
       ( RECORDS DELIMITED  BY NEWLINE
         LOGFILE YOUR_DIRECTORY:'your_log.log'
         BADFILE YOUR_DIRECTORY:'your_bad.bad'
         FIELDS TERMINATED BY ','
         MISSING FIELD VALUES ARE NULL )
     LOCATION (YOUR_DIRECTORY:'your_file.csv')
  )

Note that anything with the word "your" in it above must be changed to whatever you want to name your files and directories. Also note that "YOUR_DIRECTORY" is an actual database object you must create:

CREATE OR REPLACE DIRECTORY YOUR_DIRECTORY AS 'C:\workspaces\test\XL2ExternalTables'
