NUMBERS is a spreadsheet format: it stores data in the NUMBERS format. TXT is a document format that contains raw Unicode or ASCII characters with no embedded formatting, fonts, or layout information. This converts the tabular data into a fixed-layout document suitable for printing or sharing. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. Converting between these two formats is common when the source application does not support TXT natively or when the target platform only accepts TXT. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
