Sheet 07 · Use case

The spreadsheet you run on today, as a real app.

That tracker, intake list, or little CRM living in a spreadsheet already holds your process. Hand it to the coding agent you use, and Synthonic turns it into a real app: a database, a live URL, multi-user access, and an AI operator. No engineering.

You need A CSV or spreadsheet you already keep, and a coding agent you already use (Claude Code, Codex, any harness). Zero engineering.

What changes

What a spreadsheet can't be.

Everything on the left of that arrow is the ceiling of a spreadsheet. Everything on the right is a real app.

01
A real database, not a grid
Validation, durable records, and relationships behind the interface. Data keeps its shape and survives — no fragile formulas, no accidental overwrite of a whole column.
02
Multi-user, with rules
Share a live URL, not a file with ten conflicting copies. Coworkers use the same app, and who-can-do-what is an explicit policy, not the honor system.
03
An AI operator, over MCP Roadmap
On the way: connect an AI collaborator to the app's /mcp endpoint to read and write records, bounded by a default-deny policy, so the tool is run by an AI, not just filled in by hand. Today the access model already carries the least-privilege agent role it will use.
04
A purpose-built interface
A board, a form, a tracker — the view your process actually wants, instead of bending everything into rows and tabs.
05
Cheap to keep changing
Need a new field or view? Your agent edits the folder and redeploys — a failed build is the gate, with the errors to fix. Automatic snapshots of your data before every change are on the roadmap.
How it works

From a CSV to a live app.

Your agent does the work. You react to a running app, not a blank page.

01

Hand your agent the spreadsheet

In Claude Code or any harness, give it the file and say what the tool should do.
you → turn my accounts.csv into a sales pipeline: a drag board by stage
agent → read 3 columns, 40 rows · wrote sales/ (schema, views, policy, instructions)
02

Deploy it

Your agent runs the CLI. Synthonic interprets the folder into a real app and prints the URL.
synthonic deploy
  packaging sales/ ... seeding 40 rows
  ✓ live at  yourtool.synthonic.app
03

Share it and run it together

Send the URL to your team — each signs in as the member and role you list. Handing an AI collaborator the /mcp endpoint to operate it too is on the roadmap. See the full procedure →

Turn your spreadsheet into a real app.

Guest by default, no signup. Bring the agent you already use, and the spreadsheet you already keep.
