Informazioni su questo servizio
Messy data costs you hours before you can even start analysing it.
I clean Excel and CSV files so you get something you can actually work with: consistent formats, no duplicates, standardised units, dates that parse, and columns that each mean one thing.
What makes this different ?
You don't just get a cleaner file. You get a short report listing every issue found, how many rows it affected, and exactly what I changed. If a client or an auditor asks why a number moved, you have the answer.
What I fix ?
- Duplicates and near-duplicates
- Inconsistent dates, currencies, capitalisation
- Mixed units inside one column
- Numbers stored as text
- Hidden characters and stray whitespace
- Columns holding several facts, split out properly
- Placeholders ("N/A", "-", "unknown") resolved
- Missing values handled with a stated rule
Background
3 years in data quality and governance for banking at Societe Generale. Now a data governance consultant. Engineering degree in Data & Knowledge Science. I work in English and French.
Tools: Excel, Python (pandas), SQL, Power BI.
Message me your file before ordering and I'll tell you honestly what is fixable and what is not.
FAQ
What counts as an "item"?
One item = one column. Row count is unlimited: send me 200 rows or 200,000 and the price is the same. What drives the work is how many columns need fixing and how many distinct problems they contain.
Will you delete rows without telling me?
No. Nothing is removed silently. Every change is listed in the report with the number of rows affected, so you can reverse any decision you disagree with.
Can you work with confidential data?
Yes. I can work with anonymised or partially masked files, and I will tell you upfront which columns I actually need to do the job.
What if I don't know what's wrong with my file?
hat is the normal case. Send it over before ordering and I will tell you what I find, what is fixable, and which package fits. No obligation.
Do you work in French?
Yes. Communication and the quality report in French or English, whichever you prefer. I also speak Arabic.
Can you re-run this every month?
The Premium package includes a documented Python script so you can re-run the same cleaning on next month's file yourself. I also take recurring work directly. The frequency is adjustable.
