Sheet2API Bridge.

Democratizing Data Access: The Sheet2API Protocol

In the modern "No-Code" ecosystem, the ability to rapidly prototype applications is limited by backend complexity. Sheet2API eliminates this barrier by transforming a standard Google Sheet into a fully functional JSON REST API. This serverless architecture allows developers to use a spreadsheet as a headless CMS, powering websites, mobile apps, and industrial dashboards with zero infrastructure cost.

Technical Architecture and Security

Unlike third-party services that require you to share your data with an external server, Sheet2API operates on a **Local-First Model**. The backend code (provided below) is deployed within your own Google Workspace account. This ensures that your proprietary data never leaves the Google Cloud perimeter, satisfying strict **Data Sovereignty** requirements for enterprise usage.

function doGet(e) {
  const ss = SpreadsheetApp.getActiveSpreadsheet();
  const sheet = ss.getSheets()[0];
  const data = sheet.getDataRange().getValues();
  const headers = data.shift();
  
  const json = data.map(row => {
    let obj = {};
    headers.forEach((h, i) => obj[h] = row[i]);
    return obj;
  });
  
  return ContentService.createTextOutput(JSON.stringify(json))
    .setMimeType(ContentService.MimeType.JSON);
}

function doPost(e) {
  const p = JSON.parse(e.postData.contents);
  const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
  sheet.appendRow(Object.values(p));
  return ContentService.createTextOutput("Success");
}
