Excel to API From Any CSV or XLSX Sheet

Upload an Excel or CSV file and get a real API with typed fields, filtering, keys and docs. The demo reads your file in your browser, so nothing is uploaded until you decide.

How a sheet becomes an API

The header row becomes field names.
Types come from the first 50 rows: numbers, dates, booleans, emails and text.
Each sheet becomes a resource, and repeated values can become a related resource.
You review and correct every type before you deploy.

What the Excel to API output includes

Endpoints to list, filter, read, add and update rows.
Validation from the inferred types.
API keys and rate limits, so tools and partners use the data without the file.
Interactive docs and a mock server.
MCP tools, so agents answer questions from the data. See custom mcp server.

From a sheet to a database

Hosted APIs store the rows in a managed database, so the sheet stops being the source of truth. When you outgrow it, export the code with its schema. Teams that already have a database start on api database.

Questions about excel to api

CSV and XLSX. The demo reads the first sheet of an XLSX file, and in your workspace every sheet becomes a resource.

No. The demo parses the file in your browser. It leaves your machine only when you create a project.

Yes, through the generated endpoints or by uploading a new version of the sheet.
