Office Converter

Office Converter (@DocConverterBot) goes further than most bots in this category by publishing an actual list of supported file types in its bio: .doc, .docx, .odt, .txt, .xls, .xlsx, .ods, .csv, .ppt among others. That level of specificity is rare and useful — it tells you upfront whether your file type is even in scope, instead of finding out after uploading.

It also links to a dedicated update channel, a small but genuine signal that someone is actively maintaining it rather than having abandoned the project after launch. The core job is what the name promises: converting between common office document formats, most likely centred on getting everything into or out of PDF.

Because the exact conversion pairs (which format converts to which) are not spelled out beyond the supported-file list, it is worth sending a test document first before relying on it for something important, especially with less common formats like .ods or .csv.
