Frequently asked questions
Why split a table?
Many programs only accept a certain number of rows on import, e.g. newsletter services or web shops. Once split, each file stays below the limit.
Is the header row in every file?
Yes, if “First row is the header row” is switched on. It then doesn’t count towards the rows per file.
Is my file uploaded?
No. Splitting happens in your browser, the file never leaves your device.
