You will get clean, organized data and a clear Excel or Google Sheets dashboard
Project details
Is your spreadsheet a mess of inconsistent dates, duplicates, and numbers stored as text? I'll turn it into clean, reliable data — and a clear dashboard you can actually make decisions from.
What you get:
• Clean, standardized data — fixed dates, removed duplicates, consistent categories, proper number formats
• A dashboard with the KPIs and charts that matter to you
• Everything built on formulas (SUMIFS, XLOOKUP, pivot tables), so your report updates automatically when you add new data — no manual numbers locked in
• Works in Excel or Google Sheets, delivered in your preferred format
How it works:
You send your file and tell me what the report should answer
I clean and restructure the data, then build the dashboard
You get a clear "before vs. after" so you see exactly what changed
Fast turnaround, clear communication, and fluent English & Polish. Not sure how you want it structured? I'll suggest a sensible approach and confirm with you first.
Send me your file — let's turn that mess into something you can use.

About Jakub
Data Cleaning & Dashboards | Excel & Google Sheets
Poznan, Poland - 4:22 am local time
I help small businesses and busy professionals clean up disorganized data and turn it into clear dashboards and reports — in Excel or Google Sheets.
What I can do for you:
• Clean and standardize messy data — inconsistent dates, duplicates, mixed formats, broken numbers
• Build automated dashboards and summary reports with charts
• Set up formulas (SUMIFS, VLOOKUP/XLOOKUP, pivot tables) so your sheet updates itself
• Merge and reconcile data from multiple files or sources
How I work: I send you a clear "before vs. after" so you see exactly what changed. I build everything on formulas — so when your data changes, the report updates automatically, with no manual numbers locked in. I respond quickly, ask the right questions up front, and hit deadlines.
Send me your file and tell me what you need at the end — I'll tell you exactly how I'd approach it.
Fluent English & Polish · Available 10–25 hrs/week
