Help

When should I use Excel to JSON conversion?

Use it when you need to turn Excel-managed product lists, order data, member information, or statistics tables into API test data, frontend mock data, or development JSON files.

What is grouping all sheets?

It converts every sheet in the Excel file into an array and wraps them into one JSON object using sheet names as keys. This is useful when you want to keep multiple sheets structured together.

What does using the first row as keys mean?

It means using the first row of the sheet as property names in each JSON object. For example, if the first row is name,email, each row becomes an object with name and email keys.

Are Excel styles included in JSON?

JSON stores data structures, so visual styles such as colors, borders, merged cells, and fonts are not included. This tool creates JSON data from cell values.
