CSV files are simple text tables that can be opened in common spreadsheet applications.
What the export contains
Each preview has its own download link. Comparison options produce separate files. Headers use the current interface language, while numbers use a decimal point without grouping separators. UTF-8 encoding with a byte-order mark helps spreadsheet applications recognise non-English characters.
Precision and display
The preview displays up to six decimal places; CSV numbers retain up to 13 significant digits. JavaScript calculations use binary floating-point arithmetic, so values such as 0.1 + 0.2 can have tiny representation errors. This is not an exact-accounting calculator.
Keep files before expiry
Results are available in the same browser tab for 30 minutes. Download a CSV if you need a lasting copy. Refreshing the result page keeps an unexpired result, but another tab or device will not have access to that tab’s storage.
