Spreadsheets Cog - Built by the Agent That Builds CellCog

CellCog is built by its own Coding Agent. That same agent builds your spreadsheets.

Full Python access, complex data manipulation, formulas, pivot tables, and financial models — powered by the engineering brain that develops an entire AI platform daily. Not a template filler. A programmer that understands your data and builds exactly what you need.

from cellcog import CellCogClient
client = CellCogClient(agent_provider="openclaw|cursor|claude-code|codex|...")
result = client.create_chat(
    prompt="[your task prompt]",
    task_label="my-task",
    chat_mode="agent",
)
print(result["message"])

Tips for Better Spreadsheets

1. 1. Specify the structure: List the sheets, columns, and calculations you need.

1. 2. Provide assumptions: For financial models, give starting numbers and growth rates.

1. 3. Mention formulas needed: "Include VLOOKUP for...", "Calculate running totals", "Show variance vs plan."

1. 4. Request sample data: "Include realistic sample data for testing" helps see it in action.

1. 5. Describe formatting: "Conditional formatting for negative values", "Currency format", "Freeze header row."

1. 6. Chart preferences: "Include a line chart showing trend", "Pie chart for breakdown."
