I will clean and format your excel or CSV data
About this Gig
Turn an inconsistent spreadsheet into a clear, usable file.
I will clean one Excel or CSV file using rules agreed with you: tidy headers and spacing, standardise dates and numeric fields, review duplicates using your chosen key and flag missing or ambiguous values.
You receive a cleaned XLSX file, the retained source data and concise review notes. I do not invent missing information or silently remove uncertain matches.
My gallery shows a working demonstration: 14 source rows, 12 unique orders, duplicate decisions, a missing-price flag and editable formulas. It uses fictional data.
Packages cover one worksheet and the listed row and column limits. Send the file and rules before ordering if the structure is unusual. Complex macros, external integrations and accounting decisions are outside these packages.
I use AI-assisted and scripted tools, then verify the result against the source and agreed rules. A revision corrects or adjusts the agreed scope; new data or new requirements need a new quote.
FAQ
What counts as one cleaned item?
One item means one source data row. The package also limits the number of columns. Basic covers 100 rows x 8 columns; Standard 500 x 12; Premium 1500 x 15. Each package covers one worksheet.
How do you handle duplicates and missing values?
We agree the duplicate key and retention rule first. Confirmed duplicates are removed from the cleaned sheet, while the source is retained. Uncertain matches and missing values are flagged rather than guessed.
Do you use AI or automated tools?
Yes. I use AI-assisted and scripted tools, then verify the output against your source and agreed requirements. Tell me before ordering if your project has restrictions or needs a different workflow.
