I will clean excel and CSV data and remove duplicates
Excel Data Cleaning, Price Research and German Product Copy
About this Gig
Get a cleaned Excel or CSV file with duplicates removed, consistent formats and a clear change summary.
Packages for straightforward, structured data:
- Basic: up to 100 records
- Standard: up to 5,000 records
- Premium: up to 10,000 records
A record is one data row, excluding the header. Each package covers one worksheet or CSV. Basic includes 1 revision, Standard 3, Premium 4, within the agreed scope.
There is no fixed column cap. Price depends on data volume and the cleanup work. Send a sample before ordering if your file is unusually wide, has complex rules or multiple sheets, or exceeds 10,000 records. I will review the scope and offer a custom quote.
I apply agreed duplicate, spacing, capitalization and date/number-format rules. Identifiers and leading zeros are preserved. Missing or unclear values are flagged, never invented. You receive a cleaned copy and change summary.
I check each delivery against your instructions. English and German communication are available. Web research, PDF extraction and complex formulas/macros need a separate scope.
