Hi All, I've just released a Chrome Extension that converts CSVs to XLSX automatically (works for any site, not just NetSuite). It's now approved and public on the Chrome Extension Store (also free and open-source for transparency). https://chrome.google.com/webstore/detail/auto-convert-csv-to-xlsx/bpcbpnlhalnkaheioffegmhhdlmooieg NOTE - After installation you need to open the extension options and ENABLE 'Allow access to file URLS' so it can access the downloaded CSV and convert it. I've put more details on my post on the NetSuite reddit forum if you want further info (this was last week prior to it being public) ... https://www.reddit.com/r/Netsuite/comments/ksfgyt/download_files_as_xlsx_chrome_extension/ Enjoy! :)
