Our spreadsheet specialists clean and restructure Microsoft Excel and Google Sheets files that suffer from formatting problems, hidden duplicate rows, broken cells, or confusing layouts. We work methodically so your datasets come out organised and ready for daily tracking or analytics reporting.

We support businesses of every size, from independent freelancers to internal corporate teams and online retailers. Every project involves careful auditing of the data, trimming of stray text, separating mixed fields, and rearranging the underlying schema so the final file is easy to use.

Three service tiers

1. The entry tier handles core Excel cleaning, layout repair, and duplicate removal for spreadsheets containing up to 500 rows, delivered as a verified clean XLSX file. Larger files can be upgraded for a flat fee of ten dollars per extra 500 rows.

2. The mid-level tier adds formula checks, cell validation, filtering, custom sorting, text trimming, and conditional formatting for larger datasets reaching up to 2,500 rows, again delivered as verified clean XLSX.

3. The top tier covers full advanced cleaning, macro automation, unlimited correction of layout errors, complex string adjustments, and thorough duplicate elimination for master files up to 5,000 rows, with faster turnaround.

We aim for spreadsheets your team can trust. A portfolio of anonymised before-and-after samples is available to review our cleaning and formatting standards before you order.

Questions people ask

What happens if my Excel spreadsheet data file exceeds the specific row limits of the chosen package?

If your file goes beyond the row limit of your chosen tier, for example a 600-row file submitted under the 500-row entry package, you can request an upgrade through our messaging system. Extra rows beyond the tier threshold are billed at a flat rate of US$ 10 per additional 500 rows, so your project continues without delay.

Do you provide a formal data confidentiality guarantee, and are you willing to sign a Non-Disclosure Agreement (NDA)?

Confidentiality is central to how we operate. We apply strict data protection practices to every corporate spreadsheet and dataset we handle, and we are ready to sign a Non-Disclosure Agreement before receiving any sensitive files or procurement documents.

Do you provide verifiable before-and-after samples to demonstrate your Microsoft Excel data cleaning and formatting quality?

Yes, our portfolio gallery includes verifiable before-and-after examples showing our approach to text trimming, layout correction, and duplicate removal, so buyers can assess our standards before placing an order.
