I will clean your excel, CSV or CRM data with a full change log
Data Cleanup, B2B Research and QA Automation
I clean messy Excel, CSV and CRM data and document every change, using the discipline of 8 years in QA and test automation. My tools include C#, .NET, Selenium, NUnit, RestSharp, Postman, SQL, Azure D...
About this Gig
Messy spreadsheets break CRM imports and reports. I clean Excel, CSV and CRM exports (contacts, products, inventory) and show you exactly what changed.
What you get:
- A cleaned .xlsx file, with code columns kept as text so leading zeros survive
- A Change Log sheet listing every edit
- An Exceptions sheet for anything I could not safely fix
- Duplicate groups flagged for your decision, never deleted silently
- A short QA summary: rows in and out, and the checks I ran
What I fix: spacing and capitalisation, date and number formats, phone and country formats, units and currency columns, split or merged fields, and duplicate records.
Why me: I have 8 years in QA and test automation, so I treat your data like a test case. I check row counts, keep IDs intact, and never guess at ambiguous values such as 03/04 dates.
Please message me with a 20-row sample before ordering, so I can confirm scope and the right package.
FAQ
Will you delete duplicates?
No. I flag them in a separate sheet so you decide; nothing is removed without your approval.
What if my dates are ambiguous (e.g. 03/04/2025)?
I list them as exceptions unless you tell me the format (DD/MM or MM/DD).
Which CRMs do you support?
Any CRM that imports CSV or Excel. Tell me the target import template and I'll match its columns.
Is my data kept private?
I use your file only for your order and delete my working copies after delivery on request.
Can you work with Google Sheets?
Yes, share an export or a copy; I deliver .xlsx or .csv.
