HTMLtoCSV is a handy Chrome extension developed by oldjamey. It falls under the Browsers category and specifically the Add-ons & Tools subcategory. As the name suggests, this extension allows users to easily export HTML tables as CSV spreadsheets.

With HTMLtoCSV, you can scrape HTML tables from the current web page and quickly download each table as an individual CSV file. The process is simple and straightforward. First, you need to navigate to the web page with the data you want to export. Then, click on the ultraball icon provided by the extension. This will extract all the tables from the page and add download buttons for each table to export as CSV.

When you click on the "Download as CSV" button, the HTML table will be saved as a CSV spreadsheet. The extension preserves all column headers and attempts to retain as much formatting as possible in the CSV format.

While HTMLtoCSV focuses on providing a streamlined and efficient workflow, if you require more advanced features and editing capabilities for your spreadsheets, you may want to consider using "Instant Data Scraper" (note that it is not affiliated with HTMLtoCSV). However, if your primary need is to quickly export HTML tables to CSV, HTMLtoCSV is a reliable and straightforward solution.
