I will import, migrate and clean your excel or CSV data into a database
Software Developer
À propos de ce service
Do you have data trapped in messy Excel or CSV files that needs to live in a proper database? I can help.
I am a developer with 13+ years of experience building data tools for manufacturing and ERP systems. Moving spreadsheet data into a clean, reliable database is exactly what I do.
WHAT I DO FOR YOU:
- Import Excel (.xlsx) or CSV files into a database (SQLite, MySQL, Firebird, Access)
- Migrate data between formats and databases
- Validate and clean your data: remove duplicates, fix wrong types, flag missing values, standardise dates and numbers
- Deliver a clear report of what was imported and what was skipped (and why) no silent errors
- Optionally build a reusable script so you can repeat the import yourself anytime
WHY ME:
- Real validation, not a blind copy-paste. Every row is checked.
- Parameterised, safe queries your data is handled properly.
- Fast turnaround and clear communication.
- I treat your data as if it were my own production system.
Not sure if your files fit? Send me a message with a sample (a few rows is enough) and I will tell you honestly what is possible and how long it will take before you order.

FAQ
What databases do you support?
SQLite, MySQL, Firebird and Access. If you use a different one, just ask — I can usually work with it.
My Excel file is messy. Is that a problem?
No — cleaning up messy data is part of the service. Duplicates, wrong types, missing values and inconsistent dates are all handled.
Will I see what happened to my data?
Yes. Every order includes a report showing exactly which rows were imported and which were skipped, with the reason for each.
Can you make something I can reuse myself?
Yes — the Premium package includes a reusable script with documentation, so you can repeat the import whenever you need.
Can I send a sample first?
Please do. A few sample rows let me give you an accurate quote and timeline before you order.
