A quick variation on Frederick Vallaeys' Google Ads script that uses a dynamic field in the DURING clause for the date today

AWQL to Spreadsheets - Dynamic YTD Reports

/** 
> Export YTD data dynamically using AWQL
> Based on the AWQL to Spreadsheet script by Frederick Vallaeys of Optimyzr.com 
> Original post: https://www.optmyzr.com/blog/a-script-to-put-any-adwords-data-in-a-spreadsheet/
> The start date is static, the end date is equal to the date today

IMPORTANT:
> Make sure that you fill in the spreadsheet URL and tab name in lines 24 and 25 for the export
