# sample-data

Mock datasets for building and demonstrating dashboards. **Everything here is generated** — no real
company, person, or number appears in it.

Two shapes, because a dashboard is usually asked to do two different things.

## `sales.xlsx` / `sales.csv` — 6,402 rows

Two years of daily orders, 2024-08-01 to 2026-07-31.

| Column | |
|---|---|
| `Order ID` | `ORD-10000` upward |
| `Date` | ISO, one row per order |
| `Region` | North · South · East · West · Central |
| `Category` | Hardware · Software · Services · Accessories |
| `Product` | four per category |
| `Channel` | Direct · Partner · Online |
| `Sales Rep` | six names |
| `Units`, `Unit Price`, `Revenue` | `Revenue = Units × Unit Price` |

**It has deliberate shape, so a chart of it proves something.** A Q4 lift and a summer dip, quiet
weekends, steady growth across the two years, and one region — East — pulling ahead only in the second
year. Price ranges differ per category, so the mix moves the average.

## `subscriptions.xlsx` / `subscriptions.csv` — 480 rows

A customer list, for the other half: cohorts, MRR, churn.

| Column | |
|---|---|
| `Account ID`, `Company`, `Country` | eight countries |
| `Plan`, `MRR` | Starter 19 · Team 79 · Business 249 · Enterprise 900 |
| `Seats` | |
| `Started`, `Cancelled` | `Cancelled` is empty for live accounts |
| `Status` | Active · Cancelled |

**Churn is not evenly spread** — Starter churns about a third, Enterprise well under a tenth, which is the
pattern anybody reading it expects to find. "Active" is a calculation over dates, not just a column to
filter on, which is the point of including both.

## Both formats, on purpose

The `.xlsx` files are the realistic input — people have spreadsheets. The `.csv` twins are identical data
and need no parser, so an app can read them with nothing installed. Pick per what you are building; do not
assume the Excel one has to be converted first.

## Regenerating

`generate.ts` writes all four from a fixed seed, so a re-run is byte-identical and any diff means the
generator changed. It has no dependencies — an `.xlsx` is a zip of XML and it writes one directly, which
is why nothing had to be installed to produce these.

```bash
bun run generate.ts .
```
