Small CSV tasks should not require uploading a client file to another server.
I built a free browser-based CSV Column Extractor for the common moment when you only need one field from a spreadsheet: email addresses, product SKUs, names, or statuses.
It can:
- detect the available columns
- remove blank values
- keep only unique values
- download the result as a simple text file
The file is processed locally in the browser. Nothing is uploaded or stored.

Excel PivotTable — Sales Summary
Client had raw sales data (14 rows across UK/USA, split by quarter) and needed it turned into something actually usable. I cleaned it up and built a PivotTable that breaks total sales down by rep and country, with grand totals for both.
What I did:
Structured the raw data into a proper table (consistent headers, currency formatting)
Built a PivotTable summarizing Sum of Sales by Last Name and Country
Used SUMIFS so the totals update automatically if the source data changes — nothing hardcoded
Checked every formula for errors before delivery
Delivered as a working .xlsx file, ready to plug into a bigger report or dashboard.
If you've got messy sales/ops data sitting in a spreadsheet and need it turned into something you can actually read at a glance, this is exactly the kind of thing I can help with.
A clean spreadsheet isn’t enough if nobody can verify what changed.
I built a small CSV and Excel cleanup demonstration around a 12-row messy customer export. The workflow:
• preserved all 12 source rows
• separated 5 accepted rows from 7 review rows
• logged 39 cell-level changes
• flagged 5 validation issues
• identified 2 duplicate groups
• reconciled every input row to the delivery
The point isn’t the tiny dataset—it’s the delivery standard: assumptions, exceptions, change log, reconciliation, and repeatable tests.
If you have a messy Excel or CSV export, I’m offering a tightly scoped first cleanup starting at $25:
