よくある質問と回答
Why do European CSV files use semicolons instead of commas?
In most European countries, the comma is used as the decimal mark (e.g. 12,50 €), so semicolons are used to separate spreadsheet columns.
Are my files uploaded, analyzed, or stored on NexVaani servers?
Where supported, tool inputs and files are processed locally inside your web browser using WebAssembly and HTML5 Canvas. Your files are not uploaded to NexVaani file-processing servers.
