API Spreadsheets is a web app spreadsheet tool that allows anyone to generate an API code from their excel file. It is really easy to use and free for files under 10,000 rows. After you upload a file, you can choose between 3 different API outputs - Record JSON, Matrix (2D Array), and Column JSON, each with a link as well. Furthermore, there is also the option to get code samples in Python, R, and REST. Lastly, this service is very useful to easily obtain a database from any spreadsheet file.
