Google Sheets

Google Sheets exposes spreadsheet data through an API. LocalCloud provides a read-only values API for testing applications that consume tabular fixtures.

When to use Google Sheets

Typical uses

Use when an application consumes small, human-maintained lookup tables through A1 ranges. Seed read-only spreadsheet fixtures locally to test how those rows are interpreted.

Examples

  • Spreadsheet-backed lookup data
  • Deterministic fixtures for data consumers

Local workflow

Example usage

Install the CLI, start LocalCloud, and export its environment in the same shell. Generated endpoints account for remapped ports.

1. Install and start · shell
curl -fsSL https://local.cloud/install.sh | sh
localcloud start --local-only
# Export GOOGLE_CLOUD_PROJECT and SHEETS_EMULATOR_HOST
eval "$(localcloud env)"

Read a configured lookup range

  1. Seed a spreadsheet and an exact A1 range.
  2. Request that range with values.get or values.batchGet.
  3. Check the returned rows in the consuming application.

Documented workflows

  • Exact A1-range reads: values.get and values.batchGet

Service boundaries

  • Read-only auxiliary fixture API
  • No spreadsheet metadata, writes, range slicing, or formulas
  • No Google OAuth authority

Code examples and integrations

Start with the local guides. Official Google Cloud samples may need endpoint changes and can cover features outside the workflows listed here.

Integration

Build an integration test loop

Start the runtime, verify readiness, exercise your SDK, and clean up test state.

Agent testing

Use Google Sheets with an AI agent

Before the agent changes application logic, have it create local Google Sheets state, read it back with the project SDK, and note which feature the check covered. That first local call catches accidental production routing and needs no GCP account, service-account key, or billing project.

Configure this repo

Set up this repository to use LocalCloud for local GCP development. First read https://local.cloud/ai/agents.md, then inspect this repo, identify the GCP services and SDK language, configure emulator environment variables, and run the narrowest integration test against localhost. Do not use real GCP credentials or production endpoints.

Production endpoints, auth, IAM, quotas, regional behavior, and final release validation still need the target Google Cloud project.

Agent resources has more prompts and the AGENTS.md template.
