WorkbookDiff
Compare two Excel files and see every supported change
WorkbookDiff launched on August 1, 2026.
What it does
Compare two XLSX workbook versions directly in your browser. WorkbookDiff separates value changes from formula-expression changes, detects added or removed sheets, visibility changes, hidden rows and columns, and used-range updates, then exports a searchable CSV difference report. No signup is required, files stay in browser memory, and the product clearly lists unsupported formats and workbook features.
Compare two XLSX files online and find changes in values, formulas, worksheets, hidden rows and columns. Free, no signup, and files stay in your browser.
Use the live tool for two same-layout XLSX versions, review formula changes separately, or tell us when your real job is matching reordered rows by an ID. Choosing a task helps us improve the right workflow. No workbook data is collected. Compare values, stored formulas, sheets, visibility, hidden rows and columns. Focus on changed formula expressions between two aligned XLSX versions. For reordered rows, missing records, invoices, SKUs, orders, or migration checks. Best fit: two versions of the same workbook with stable row and column positions. If rows moved, use the ID-matching demand test above. The compared workbook content and supported structural signals match. This comparison covers…from workbookdiff.com

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
