Spreadsheets to JSON in One Click

Google Workspace Add-on

Convert Google Sheets to clean, structured JSON with nested objects, arrays, and smart type inference. No coding required.

One-time payment. Free updates forever.

Smart header parsing

Use dot notation for nested objects and brackets for arrays.

Headers like name, address.city, tags[0] become:

{
  "name": "John",
  "address": { "city": "NYC" },
  "tags": ["developer"]
}

Powerful conversion with zero configuration.

Two Output Formats
Array of Objects or Array of Arrays. Choose what fits your needs.
Nested JSON
Use dot notation in headers to create nested objects automatically.
Type Inference
