FAQ & CSV Formats

A simple guide to preparing and importing your telemetry data files.

How do I import data?

To view your telemetry data (such as pressure, temperature, or sensor levels) as interactive line charts or digital circular charts, you just need a standard CSV file.

First Row: Must contain the column headers (labels like Time, Pressure, Temperature).
First Column: Must represent when the measurement occurred (the time).
Remaining Columns: Contain your numbers/metrics data.

Smart Auto-Detection

Plotz99 has a built-in smart parser that reads your file and automatically configures the timeline without you having to adjust any settings. Here are the timelines we support:

1. Standard Date & Time

Classic calendar date and time. It can be formatted with dashes or slashes.

Time,Pressure,Temperature
2026-07-12 10:00:00,45.2,82.4
2026-07-12 10:05:00,46.1,82.6

2. Two-Column Date & Time

If your date is in column 1 and time is in column 2, the parser automatically combines them.

Date,Time,Pressure,FlowRate
2026/07/12,10:00:00,620,12.5
2026/07/12,10:15:00,625,12.8

3. Relative Offset (Elapsed Time)

Ideal for lab tests or simple cycles starting at zero. The parser reads relative hours, minutes, or seconds.

Seconds,Pressure,Flow
0,10.2,0.5
5,15.6,0.8
10,22.1,1.2

4. Duration or Timestamps

Unix epoch timestamps (e.g. 1783857600) or duration intervals like `01:30:00` are also fully supported.

Duration,FlowRate,Temp
00:05:00,5.2,74.5
00:10:00,5.8,75.1

Tips for Best Performance

No Text in Data Rows: Make sure columns containing pressure, temperature, etc. contain only numeric values (like 45.2, not 45.2 psi).
Remove Blank Rows: Ensure there are no empty rows at the bottom of the CSV file.
Local Safety: All data is parsed right inside your web browser using a secure local Database engine. Your telemetry data is never uploaded to any remote web server.
