About this Gig

Need to combine spreadsheet exports without losing track of your records?


I will clean and merge up to 3 CSV, TSV or plain XLSX files, with up to 100 data rows in total and matching columns. One explicitly named worksheet per workbook.


Included:

- Trim surrounding whitespace, remove empty rows and exact duplicate records using agreed rules.

- Preserve text IDs such as 0001.

- Flag missing required fields and conflicting IDs for your review.

- Deliver a cleaned CSV, a spreadsheet-safe viewing CSV, a row-source audit and a summary report.


Conflicting IDs are retained, not guessed or silently combined. Output is CSV, not a reformatted Excel workbook.


Please message me on Fiverr with an anonymized sample and your rules before ordering. No macros, formulas, OCR, fuzzy matching or manual research in this package.


I use an AI-assisted custom tool and review the output. Your files are processed locally and are not sent to an AI model. Portfolio examples use fictional data.
