I will build custom google sheets automation with apps script appsheet and webhook sync

Just the one sheet, I never ask for full Drive access. You can share a single file with editor permission, or duplicate your sheet and share the copy if you'd rather keep the original untouched during development.

Yes, this is one of my most common requests. I audit the existing structure first, repair the broken formulas and references in place, and only rebuild the parts that are truly beyond saving, your historical data stays intact.

Apps Script and the platforms I build on (AppSheet, Glide, Looker Studio) are Google-maintained and generally stable, but if a Google-side change ever breaks something within 30 days of delivery, I'll fix it at no extra charge under the delivery guarantee.

No, a free personal Google account works for most Apps Script automations and formula fixes. Some AppSheet/Looker Studio features and higher script execution quotas do benefit from Workspace, and I'll flag it upfront if your specific build needs it.

Absolutely that's the goal. I design automations to run quietly in the background or through simple buttons/menus, so your team keeps entering data the way they always have without needing to understand the script underneath.

I build with your expected scale in mind from the start, using efficient batch operations instead of slow cell-by-cell loops. If you're expecting rapid growth, tell me the projected row count upfront so I can architect around Google's execution limits rather than hit them later.

Yes, I can migrate Excel or Airtable data into Google Sheets as part of the build, or connect Sheets to sync with those tools where a full migration isn't practical. Let me know your source platform before ordering so I can scope it correctly.

No day-to-day use requires zero coding. I document any settings you might reasonably need to adjust (like changing an email address in a trigger) in plain language, and anything beyond that I'm happy to handle as a quick follow-up.
