Excel and CSV data cleaning: dedupe, standardize and fix

Data and analytics · delivered in 1-3 days

Each tier removes duplicate rows, repairs blanks and broken formats, and tidies dates and numbers into a single reliable workbook. Every order arrives with a QA report listing exactly what was changed, and we confirm scope against a sample file before work begins.

A spreadsheet riddled with duplicate entries, empty cells, inconsistent date formats and columns that will not sort properly is a liability, not an asset. PBN.LTD converts it into one dependable workbook and supplies a change log so every edit is visible and traceable.

Cleaning data properly is not a cosmetic exercise. It decides whether your pivot tables and reports can be trusted. We work the way an analyst would: standardise the structure, check the results, then document every step taken.

What is included

  • Duplicate rows identified and removed, including fuzzy matching for near-identical entries
  • Blank cells and obvious errors corrected or flagged for your decision
  • Dates, numbers, headers and categories brought into one consistent format
  • A finished .xlsx or CSV file ready for pivoting, filtering and analysis
  • A QA report delivered with every order, detailing what changed and what did not
  • Custom formatting rules available on request, covering column order, date style and category naming
  • Larger files are handled without difficulty as the process scales with the dataset

Typical jobs

Examples include tidying a CRM export, combining several monthly sheets into one file, repairing output from an older system, standardising addresses or phone numbers, splitting or joining columns, and rescuing a workbook that has been patched by hand for a long time.

How it works

  1. Share the file, or a sample of it, so we can confirm the scope and price upfront.
  2. We clean the data using a documented, repeatable method rather than guesswork.
  3. You receive the finished workbook along with the change report for your own review.

Privacy

Your information is kept solely for the purpose of completing your order and is deleted afterwards if you ask us to. If the file holds personal or sensitive details, let us know and we will follow your exact instructions for handling it.

If you are unsure whether a file can be fixed, send a sample and we will give you an honest view before anything is ordered.

What happens after you buy

Your order opens its own thread here the moment it is paid, and everything about that order - questions, changes and the final report - happens in it.

Questions people ask

Do you handle scanned or photographed data?

Sharp, typed scans convert well. Handwritten or heavily blurred pages are harder to guarantee, so send a sample first and we will confirm what is achievable before you commit.

Can you deduplicate using my own rule?

Yes, we apply both exact and fuzzy near-duplicate matching. Tell us which fields to compare, such as name, email, phone or address, and how to prioritise merges, or leave it to our judgement.

Will my data stay private?

Yes. Your files are handled only to complete your own order, are never passed on or reused elsewhere, and can be deleted on request once delivery is complete.

What if I have more data than a package covers?

Send us the file size and row count and we will put together a custom quote, often lower than expected.

Which formats work in and out?

We accept Excel, CSV, TXT and tables pulled from PDFs. You receive back one tidy .xlsx or CSV file together with the QA report of every change made.
