You will get your Google Sheets or Excel fixed, cleaned up, and running fast
Project details
A single #REF! or a formula that quietly returns the wrong number can throw off your whole sheet — and slow, laggy workbooks waste minutes every time you open them. I fix exactly that: broken formulas, errors, duplicates, and the sluggishness that comes from bloated or fragile spreadsheets.
WHAT I FIX
• Formula errors: #REF! / #VALUE! / #DIV/0! / #N/A / #NAME? — traced to the root cause
• Wrong results from formulas that "look fine" but calculate incorrectly
• Slow / laggy files — I find and replace the heavy formulas dragging it down
• Broken cross-sheet references and links
• Messy data — deduplicated, standardized, cleaned
• (Premium) Fragile manual workflows rebuilt with dropdowns, validation, and a summary dashboard
Most small fixes are quick once I can see the file. Send it over and I'll tell you which package fits.

About Blacksmith
Automation Specialist | Google Sheets, Apps Script & API Integration
Hangzhou, China - 7:47 am local time
linked dropdowns, live dashboards, and API integrations powered by Apps Script.
Most spreadsheet freelancers just write formulas. I spent 10+ years designing
enterprise systems (CRM, ERP, automation) — so I design the whole workflow
around your sheet, not just the cells.
WHAT I BUILD:
→ Multi-sheet data pipelines — e.g. a 7-sheet scheduling & payroll system with
cascading dropdowns, auto progress tracking, and a live dashboard
→ REST API → Google Sheets sync — scheduled triggers, deduplication, error logging
→ Fixing messy sheets — broken formulas, slow files, fragile manual workflows
→ Beyond Sheets — automations with Make, n8n and Notion across multiple apps
HOW I WORK:
Before I quote, I map your workflow into a clear system diagram — so you see
exactly what will be built before you pay. Every delivery comes with docs, not
just a working file.
BACKGROUND:
10+ years shipping enterprise software — chatbots handling 90% of inquiries, OCR
at 97% accuracy, CRM/ERP integrations for clients across Southeast Asia. I bring
that systems thinking to every spreadsheet job.
Send me your sheet or describe your workflow, and I'll reply with a concrete plan
within 24 hours. Based in China (GMT+8), available 30+ hrs/week.
