Create spreadsheets & documents with Cloudflare Workers

Create a shareable spreadsheet from a Cloudflare Worker using the standard fetch — no Node APIs needed. It runs at the edge with near-zero cold start, making it a great place to host a lightweight "generate a document" endpoint or a webhook relay that adds the auth header.

export default {
  async fetch(request, env) {
    const res = await fetch("https://openofficeai.com/api/v1/sheets", {
      method: "POST",
      headers: {
        "Authorization": `Bearer ${env.OPENOFFICEAI_KEY}`,
        "Content-Type": "application/json",
      },
      body: JSON.stringify({
        title: "Edge report",
        sheets: [{ rows: [["Month", "Revenue"], ["July", 48200]] }],
      }),
    });
    const { url } = await res.json();
    return new Response(url);
  },
};

How to create a spreadsheet with Cloudflare Workers

1. 1Add your API key as a Worker secret (wrangler secret put OPENOFFICEAI_KEY).
2. 2In the fetch handler, POST to /api/v1/sheets with the Bearer header from env.
3. 3Read the url from the response.
4. 4Return it, or relay incoming webhooks to the API with the header attached.

Why use OpenOfficeAI with Cloudflare Workers

• Edge runtime, near-zero cold start, global by default.
• Ideal webhook relay — add the auth header no-code tools can't.
• Standard fetch, no Node-specific dependencies.
