Full Description
Messy spreadsheet? I will clean one CSV or Excel-style file and return a usable version plus a short report showing what changed and what still needs your judgment.
Good fit for:
- customer, order, inventory, product, or contact lists
- duplicate detection and cleanup
- inconsistent dates, numbers, casing, spacing, and blank rows
- splitting or combining simple name, address, status, or note columns
- preparing a file for reporting or import
You receive:
- cleaned CSV/XLSX-compatible file
- duplicate or possible-match file when applicable
- exceptions file for rows I will not guess on
- short cleanup report with counts and notes
Starter scope:
- one file
- up to 1,000 rows
- one revision
- 48-hour delivery after scope acceptance
Before ordering, send a sample or describe the file type, row count, columns, what clean should mean, and any rules I should follow.
Important limits: I do not invent missing information. I flag uncertain rows instead of guessing. I do not accept medical, legal, banking, children's data, passwords, private IDs, API keys, or regulated/sensitive records.
How the cleanup works:
- I review the file or sample first and confirm the cleanup rules before starting.
- I keep a conservative approach so your original data meaning is preserved.
- I remove obvious duplicate rows when safe, and separate possible duplicates when they need review.
- I standardize simple formatting issues such as extra spaces, inconsistent capitalization, date formats, numeric formats, and status labels.
- I flag unclear rows in an exceptions file instead of making risky assumptions.
This is useful when you need a cleaner file for a CRM import, sales report, inventory review, email list audit, marketplace catalog, or internal handoff. The goal is not just to make the sheet look nicer, but to make it easier to trust, filter, import, and explain.
Please include any rules that matter, such as which column is the unique ID, whether phone numbers should keep country codes, whether names should be title case, and which columns should stay untouched.

Spreadsheet Cleanup — Synthetic Before & After
Synthetic portfolio demonstration created for TidySheet Sprint. A five-row customer CSV was cleaned conservatively: one exact duplicate was removed, inconsistent formatting was standardized, and three rows needing human judgment were flagged. Deliverables include the cleaned file, duplicate and exception outputs, and a cleanup report. No paid-client or sensitive data was used.

Frequently Asked Questions
The file itself - one CSV or Excel file, up to 1,000 rows - plus a short note on what it is for or how you want the columns to end up. I confirm the scope with you before any work starts.
Message me with the rough size first. I will tell you whether it fits this package or whether it needs a separate quote - I will not start work outside the listed scope.
No. Anything ambiguous is flagged in the exceptions file with a note on what was unclear, and left for you to decide. I do not invent or fill in missing data.
Exact duplicates are removed and listed in a duplicate report. Possible matches - like near-identical names or email addresses - are flagged for your review instead of being deleted automatically.
No. Never send passwords or account credentials. Send the file itself, or an export of it - I do not need access to your accounts.
No - no ID numbers, payment or bank details, health records, or other regulated data. If your file contains any of these, send a stripped-down copy instead.
One revision is included. Tell me what to change and I will redo it, then send the updated files.
