How does opening TXT files locally in a browser work?

From a technical point of view, the tool only uses functions available in the user's browser. After selecting a TXT file (or log, csv, etc.), the script uses theFile APIto read its contents as text, taking into account the selectedcharacter encoding. Nothing is sent externally - the browser reads the data and shows it in the editor.

Thanks to support for UTF-8 and popular Central European encodings (Windows-1250, ISO-8859-2), you can correctly display Polish characters even in older files. If necessary, simply change the encoding from the drop-down list and the tool will load the file again, trying to decode the content correctly.
