Frequently Asked Questions

How does the CSV visualizer handle different delimiters (comma vs semicolon vs tab)?

The parser analyzes the first several lines of your file to determine whether your CSV uses standard commas (,), European semicolons (;), tabs (\t), or pipes (|), splitting the columns accurately.

Are my CSV records uploaded to any server or external database?

No. All parsing, data aggregation, and chart rendering execute 100% locally inside your browser memory (RAM). No data is sent over the network.

How large of a CSV file can I visualize in my browser?

Our optimized streaming parser comfortably handles CSV files with up to 250,000 rows (approx. 50MB) on desktop browsers with zero upload latency.

What chart types can I create from my CSV data?

You can generate Bar Charts (categorical comparisons), Line Graphs (time-series trends), Area Charts (cumulative growth), Pie/Donut Charts (market share), and Scatter Plots (correlations).

Can I clean my CSV file if there are missing values or duplicate rows?

Yes. You can use our in-browser Data Cleaning Tool to deduplicate records, fill missing values, or drop unwanted columns with a full undo/redo history.
