Why can't I just paste standard HTML tags into my email?

Standard blocks work fine in modern browsers, but classic desktop Outlook handles HTML very differently. While it does not strip style tags entirely, Outlook heavily filters or ignores modern CSS rules, and mobile clients like Gmail often drop them completely. The only way to guarantee consistent formatting across Outlook desktop, web, mobile, and Gmail is to use inline CSS attached directly to each cell and header. FlowTableStyler handles that heavy lifting by providing dynamic HTML table styling and generating a nested Power Automate replace() expression automatically.

Yes. All table styling, expression generation, and HTML processing happen 100% locally in your browser. Your data never leaves your device, is never sent to or stored on a backend server, and we never track, inspect, or log the contents of your tables.

Do I need a premium Power Automate licence to use this code?

No. The generated expressions rely entirely on standard, free actions like Compose and Create HTML table. You do not need any premium connectors or third-party paid tools to achieve professional email formatting.

Will these tables look good on Outlook for mobile phones?

Yes. If you choose the '100% (Responsive Full Width)' option in the tool, the code ensures your table automatically adjusts to fit mobile phone screens, preventing users from having to scroll sideways to read your data.

Does this work with my data from SharePoint, Dataverse, or Excel?

Absolutely. The styling expression does not care where your data comes from. Whether you need to style a SharePoint list HTML table, extract records from Dataverse, or format an Excel spreadsheet, as long as you feed that data into a Create HTML table action first, this tool will help you make your Power Automate emails look professional.

Why do my dates and currencies look wrong inside the styled table?

This tool only controls the visual design (colours, borders, and spacing). It does not change your actual data. If your dates look like long system codes or your currencies are missing the '£' symbol, you need to use a Select action in Power Automate to format your numbers and dates before sending them to the HTML table.
