I will clean and deduplicate your excel CRM or lead list
About this Gig
Your Excel or CSV file is a mess - duplicates, inconsistent formatting, jammed columns, mismatched values across sheets. I fix it fast, using custom desktop software I built specifically for this (not manual work in Excel), so your file gets processed in seconds instead of hours, even at tens of thousands of rows.
What I handle:
- Removing duplicate rows (exact or near-match/typo detection)
- Standardizing formatting - casing, whitespace, dates, digits
- Splitting or merging columns
- Matching/aligning data across two files
- Cleaning up messy exports before they go into a report or dashboard
Why work with me:
- Purpose-built tools, not manual copy-paste - faster and more consistent, even on large files
- 100% offline processing - your data never touches a third-party server
- Clear before/after - you'll always know exactly what changed
How it works:
- Send your file(s) and tell me what needs fixing
- I run it through my tools and review the output
- You get a clean file back, plus an audit list of what was changed if needed
Not sure if your file fits neatly into a package? Message me first - happy to take a quick look before you order.
FAQ
What file formats do you accept?
CSV and Excel (.xlsx, .xls). If you have a different format, message me first and I'll confirm I can handle it.
Is my data safe?
Yes — all processing happens offline through desktop software, not a cloud service. Your file never gets uploaded to a third-party server, which matters if you're working with client or customer data.
What if my file is bigger than the package I picked?
No problem — just add the "Additional Items Tagged" extra for the extra rows, or message me first if you're not sure which package fits. I'd rather confirm than have you order the wrong tier.
What if my data is messier than the package covers (needs correction, not just dedup/formatting)?
Add the "Data Correction" extra, or message me first with a sample and I'll tell you honestly whether your package covers it or you need more.
Do you sign an NDA?
Happy to for sensitive datasets — just ask before ordering and I'll take care of it.
What do I get back?
A cleaned file in the same format you sent, plus an audit list of what was changed if you want one (just mention it in your order notes).
What if I'm not happy with the result?
Message me first — most issues are a quick fix. Revisions are included per your package tier, with extra revisions available as an add-on if needed.
