I will clean and validate excel or CSV data for business system import
About this Gig
Preparing a spreadsheet for CRM, accounting, ecommerce, or database import?
I will clean and validate Excel, CSV, or Google Sheets data so it is consistent, structured, and ready for business use, not just visually tidy.
Services can include:
- Removing duplicates, blanks, and extra spaces
- Standardizing dates, numbers, case, and text formats
- Splitting, merging, or mapping columns to a supplied template
- Preserving existing formulas
- Flagging missing, invalid, or questionable values
- Checking consistency across sheets
- Providing a short change summary
Best for customer lists, product catalogs, SKUs, accounting exports, CRM migrations, ecommerce uploads, and recurring reports.
I may use Excel, Power Query, or AI-assisted tools, but I manually review the final output against the agreed rules.
Research, scraping, missing-data completion, complex formulas, macros, dashboards, and analysis are not included unless agreed in a custom offer. Message me first for more than 3,000 rows, over 5 sheets, macro-enabled files, sensitive data, or a named-system import.
Revisions cover corrections to the agreed cleanup rules, not a new scope.
FAQ
What do you need to get started?
Upload the file and describe its intended use, problems to fix, row and sheet count, desired output, and formulas to preserve. Attach the required column template for a CRM, accounting, ecommerce, or database import.
Can you handle large datasets?
Yes. Premium covers up to 3,000 rows across 5 sheets. Message me for larger or unusually complex datasets so I can quote the scope accurately.
Can you prepare data for a business system import?
Yes, when you provide the required columns or import template. I can clean and map fields to that structure. Platform setup and executing the final import are not included unless agreed in a custom offer.
How do you handle confidential or sensitive data?
I use your files only to complete the order and do not share them. You may mask sensitive fields before upload. I can delete local working copies after delivery; files stored by Fiverr remain subject to Fiverr's policies.
