Free CSV Car Datalog Viewer
ZapData.me is a disposable datalog viewer for car CSV logs. Upload a short log, graph channels against time, inspect live hover values, pin important moments, export the view, and let the uploaded file expire after 24 hours.
The viewer is designed for tuning and diagnostic logs where RPM, boost, AFR, throttle, timing, WGDC, fuel pressure, IAT, and other channels need to be compared in one place.
Each upload gets a long private link and an automatic 24-hour countdown. You can also delete the log manually as soon as you are finished reviewing it.
Save a PNG for fast sharing, or export a one-minute interactive HTML view that keeps hover values and markers available after download.
Upload a CSV with a time column, choose the parameters you want to see, drag horizontally to zoom, click the graph to pin up to three marks, and use thresholds to spot values outside your expected range.
ZapData.me supports CSV datalog files up to 2 MB and up to 3 minutes of time-based car data.
No. Uploaded logs use long private URLs, are not indexed, and are deleted automatically 24 hours after upload.
Yes. Select or clear channels from the parameter list to compare multiple colored traces on the same time graph.
The live viewer needs the website, but exported offline HTML files can open without internet for the selected one-minute window.
Upload a CSV car datalog up to 2 MB and 3 minutes long. ZapData creates a private URL that expires 24 hours after upload.
Hover on the graph to scan values at the cursor. A vertical line follows the cursor and RPM stays at the top in red.
Use checkboxes to show or hide channels. Search filters the parameter list. Default parameters restores the first auto-selected channels.
Drag left or right across the graph to zoom into a time window. Click the graph to pin up to 3 marks. Right-click removes the newest mark. Reset zoom returns to the full log.
Enter Min or Max values beside a parameter. When the cursor or a mark is outside that range, that value flashes red faster as it gets farther past the limit.
Save static PNG captures the current graph and marks. Small online HTML is tiny but needs internet. Offline HTML is bigger but opens without internet. Interactive HTML requires a 1 minute or shorter visible window.
Copy shares the private 24-hour link. Delete log removes the uploaded log immediately. Downloaded PNG/HTML files stay on your device.
