I will clean merge and format your excel or CSV data
About this Gig
Messy spreadsheet? I will turn your Excel or CSV file into an organized, usable dataset.
Depending on your package, I can remove agreed duplicates, trim extra spaces, standardize dates and numbers, split or combine columns, and merge files with compatible layouts.
You receive the cleaned XLSX or CSV, a brief change summary, and a separate list of ambiguous records that need your decision. I keep the original source unchanged and do not guess missing values.
Basic covers 1 file, up to 100 rows and 10 columns, with up to 3 agreed cleanup rules. Larger packages add files, rows and rules. Revisions cover the original agreed requirements.
Please message me with a small anonymized sample and your desired result before ordering. Scanned PDFs, handwriting, macros and complex fuzzy matching require a separate quote.
I use AI-assisted tools where appropriate and validate the output. Portfolio examples use fictional data.
FAQ
What counts as a cleanup rule?
One agreed transformation, such as removing exact duplicate IDs, standardizing one date column, or splitting one column. The row limit is the combined input size across all files.
Which files can you work with?
XLSX and CSV files with a clear table layout. Send a sample first for password-protected files, unusual layouts or files with macros.
Will you fill missing or conflicting values?
I flag unclear records for your review. I only fill or change them when you provide an explicit rule or a reliable reference.
What is included in a revision?
Corrections needed to meet the original agreed cleanup rules. New files, new rules and a different output structure are additional scope.
Do you use AI tools?
I use AI-assisted tools where appropriate and check the results. Tell me about confidentiality requirements and any restrictions on external AI before ordering.
Are your portfolio examples real client projects?
They are original demonstrations using fictional data, clearly labeled as samples.
