Add Excel to Webflow

You’ve built a spreadsheet in Excel, saved as an .xls file, and now you want to bring it onto your Webflow site. Maybe it’s a cost estimator, ROI calculator, or pricing model. You don’t want to upload a static .xls file that people can download or break. You want a clean, interactive calculator that hides your formulas and works perfectly on any device.

If that sounds familiar, ConvertCalculator for Webflow is exactly what you need.

Common Problems with Embedding Excel in Webflow

Here’s what users on Reddit and the Webflow community are experiencing, verbatim:

Syncing sheets into Webflow CMS is tricky
“I keep running into issues comparing an existing item on the Webflow db to update instead of just creating a new one.” (reddit.com)
Many rely on Zapier, Make, or external tools like WhaleSync, and struggle with duplicate item creation or tracking updates.

Excel tables aren’t supported natively
“I thought perhaps I should copy the Excel data into a native Webflow table, but there doesn’t seem to be one.” (webflow.com)
Users wish for seamless Excel embedding, but Webflow lacks native support for tables.

Embed formatting is brittle
“I need to embed a Google Sheet… but after inserting the code… I have no control over the size—it defaults to a tiny square.” (webflow.com)
The default iframe embeds often render awkwardly, and fixing them requires manual HTML tweaking.

Live charts are hard to embed
“I am trying to post… a live chart from Google Sheets… updated on the website regularly… Is this possible?” (reddit.com)
Users resort to Integromat, Zapier, or custom code to push dynamic chart data into Webflow CMS which is brittle.

Custom code and API syncs are fragile
“I have edited custom code… but… the published site does not pull out any data.” (webflow.com)
Even minor mistakes in API keys, sheet IDs, or script placement can break the entire integration.
