People often send me different text files in different formats and demand the same format from me.
And since I don’t have every software in the world (for example I don’t like OpenOffice so I don’t have it), I had to improvise. I found this great online document viewer and converter that made all those annoying problems go away.
It’s called Zoho and it has everything I would need on this field.
It views and converts online:
Microsoft Office: doc, docx, xls, xlsx, ppt, pptx, pps; OpenDocument: odt, ods, odp; OpenOffice:sxw, sxc, sxi; Other Formats: rtf, txt, html, csv, tsv
