I am working in a company, and for some reason, I'm being dumped to do statistics. 

I'm given a load of data dumps, and I am made to do some really repetitive data massage.

The first solution, obviously, is to write a script to do this for me. I can't. I am not allowed to download servers into my PC, being a PHP programmer, I can't do this.

Secondly, I thought of importing these txt files into a MySQL database and running queries on them. Again, I can't. I'm not even allowed to have a MySQL database in my PC.

**Firstly, let me describe what I'm hoping to achieve.**
I'm given a data dump, and I'm trying to run a query similar to this:

```
SELECT SUM `price` FROM <this excel sheet> WHERE `date`>`somedate` AND `type`=`sometype`

```

I've tried to do some research on running queries on Excel, which gave me decent results. I could use autofilter/advanced filters to filter out results that are irrelevant to me. And then I can use autosum to achieve the sum of the price.

This is however, a way too lengthy process. It's much better than doing it manually, but it's not good enough for me. I am looking for a programmatical way to solve this.

Conditions: 
I cant install any apache/mySQL servers into my PC. I am however, allowed to install softwares. 

What is the best approach to solve this?
