ExportJSON-for-GoogleSheets

JSON exporter for GoogleSheets. Based on https://gist.github.com/pamelafox/1878143

Usage:

• Paste the code from exportjson.js to the Code.gs in your spreadsheet: Tools - Script Editor, save it. Reload your spreadsheet. You should be able to see a new button in the tools panel.
• Freeze your first row: View - Freeze - 1 row
• Press that new button from step 1 (it will ask for autorization and permission, allow it).

Note: if you add "TEST_" to the header's name or sheet's name, it won't be exported.
