I will clean your CSV or excel file, remove duplicates rows
Data Cleaning Specialist
About this Gig
Messy spreadsheet? Send me ONE CSV or Excel file and get back a clean, checked version - nothing invented, nothing silently deleted.
What I can do (you choose):
- Trim extra spaces in every cell
- Remove exact duplicate rows and empty rows
- Standardise dates and numbers to one format
- Make text case consistent
- Check emails and flag invalid or missing ones
- Flag rows with missing values
- Sort rows by the column you choose
How it is checked: every row and value in the result is compared automatically with your original file, and I review it before delivery. Anything that cannot be determined from your data is flagged, not guessed.
I use automated data tools plus my own review. If you require that no automated or AI tools are used, tell me before ordering.
Not included: more than one file or sheet, typing from PDFs, images or scans, formulas, pivot tables, charts, dashboards, macros, colours or styling.
Not sure your file fits? Message me before ordering - it's free.
FAQ
Will you change my data?
Only the steps you choose. Every other value is kept exactly as it is, and the result is compared with your original before delivery.
What if a value is wrong or missing?
It is flagged in a separate column, never guessed or invented.
Can you merge several files?
Not in this gig - one file per order, CSV or Excel with one sheet of data.
Do you keep my file?
Only as long as needed for the order and revisions. It is never shared.
