How can I pull data from an attached excel/csv file?

Question

I currently manage some price lists for the company I work for. They are graphical, and usually created in inDesign and then exported to pdf.
I'm looking for a way to attach our company's prices in an excel sheet, (or delimited file) and be able to pull a price into the pdf.
For example, attaching an excel file with 2 columns, SKU & Price. Then saying, if text field SKU= "APPLE" text field PRICE = "0.50". Only I don't want the user to have any inpurt options, I want to do this myself and then save a flat version to distribute in the company.
Any ideas on how this could be accomplished (if it even could be?) I've been searching for the past week.
Thank you in advance.

First, let me start off by saying thank you again for your help. I sincerely appreciate it.
I have placed the following code into the document-level section of the javascript editor:
var oFile = this.getDataObjectContents("Price.xls");
var strData = util.stringFromStream(oFile, "utf-8");
function ParseData( strData ){
var objCollection = {}
strData.replace(
new RegExp( "\\[(\\w+)=([^\\]]*)\\]", "gi" ),
function( $0, $1, $2 ){
objCollection[ $1 ] = $2;
return( objCollection );
// Custom Calculate script for price text field
(function () {
    // Get the value of the SKU field
    var sku = getField("SKU").valueAsString;
    // Look up the price
    var price = objCollection[sku];
    // Set the value of this field to the price if it's present,
    // otherwise blank this field
    event.value = price || "";
And I have created a field SKU, which I placed a valid SKU value into. I also created a blank field called event for the price to populate into, but I have a strong feeling that this was the wrong approach.
At any rate, I've recieved the following error in the javascript debugger:
ReferenceError: objCollection is not defined
89:Document-Level:ADBE::FileAttachmentsCompatibility
Any idea what I may be doing wrong?
Thanks again.
