# Serve report data from a Google Sheet as an API

Reporting data usually starts life in a spreadsheet. PasteSheet keeps it there and puts a real API in front — typed JSON, filters, sorting, and count/sum/avg summaries — so BI tools, dashboards, cron scripts, and embeds can pull metrics on demand without a warehouse, an ETL job, or a line of backend code.

## Key facts

- Google's Sheets API is **cell-oriented**: it reads ranges like `A1:D50`, not records. Reassembling those into row objects is work you do yourself. ([source](https://developers.google.com/workspace/sheets/api/limits))
- Aggregation summaries (`count`, `sum`, `avg`, `group_by`) and full-text `search=` are **Pro ($19/mo)** features; filters, sorting and pagination over typed rows work on every plan.
- Private endpoints and API keys start on **Starter ($9/mo)**: the reporting URL then requires an `Authorization: Bearer` key, so only your BI tools and cron scripts can read it.
- Report volume is capped by plan: **500 rows on Free**, **5,000 on Starter**, and no row cap on **Pro**.

## A metrics endpoint without a warehouse

Plenty of reporting never justifies a data warehouse. Weekly numbers, campaign results, NPS by month, signups by plan — someone keeps them in a Google Sheet, and everyone else copies figures out by hand. PasteSheet turns that sheet into a versionable reporting API instead: a stable URL that returns typed JSON, so the report has one source and every consumer reads it the same way.

Because the same query engine powers filtering, sorting, and [aggregation](https://pastesheet.com/features), a report consumer can ask for exactly the slice it needs — a date range, one campaign, a rolled-up monthly average — rather than pulling the whole sheet and reducing it client-side.

## Who reads the reporting API

One read-only endpoint feeds every downstream consumer of the numbers:

- BI and no-code tools that ingest a JSON URL — Looker Studio connectors, Retool, Airtable sync.
- Scheduled scripts and cron jobs that snapshot metrics or post them to Slack.
- Embedded report widgets on a status page, client portal, or [live dashboard](https://pastesheet.com/use-cases/google-sheets-live-dashboard).
- Notebooks and analyses that `fetch()` the rows for ad-hoc exploration.

## Ask for the summary you need

Aggregate at the edge so BI tools receive report-ready figures. Here average NPS and total signups per month:

```bash
curl "https://pastesheet.com/your-endpoint/Reports?group_by=month&avg=nps&sum=signups"

{
  "data": [
    { "month": "2026-05", "nps": 41.2, "signups": 1830 },
    { "month": "2026-06", "nps": 44.8, "signups": 2104 }
  ]
}
```

## Read-only, so it is safe to distribute

Because the endpoint is **read-only by design**, it is safe to expose publicly or hand to a teammate: consumers can read and query the data but can never change the sheet. And there is **no Google Cloud project, OAuth screen, or service account** to set up — you paste a share URL and get a live API.

## What it costs

**Starter — $9/month.** For indie makers shipping a real app.

- Endpoints: 10
- Requests: 50,000 / month
- Rows per endpoint: 5,000
- Tabs per endpoint: 5
- Rate limit: 300 / minute

**Start on Free** to expose report rows as JSON. Aggregation summaries (`count`, `sum`, `avg`, `group_by`) and full-text search arrive on **Pro ($19/mo)**; private endpoints and keys lock the API to your own tools from **Starter ($9/mo)**.

## Frequently asked questions

### Can BI tools connect to a Google Sheet through this?

Yes. Any tool that reads a JSON URL — Looker Studio, Retool, a custom connector — can pull the endpoint. It returns typed JSON with filtering and sorting, so the tool gets clean records instead of raw cells.

### Does it compute summaries or just return rows?

Both. Return raw rows for detail, or add group_by with count/sum/avg to get rolled-up figures computed server-side, so scripts and embeds receive report-ready numbers.

### How do I keep report data private?

Make the endpoint private on a paid plan and it requires a bearer key. Your scripts and BI tools send the key; the raw sheet is never exposed publicly.

### Can a consumer of the API change my report?

No. The API is read-only — it only serves data. Downstream tools and scripts can query and summarize the report but can never write back to the sheet.
