I&#8217;ve been working on ML\/Robotics research for a while and often work with HDF5, Parquet, and Zarr files. Personally, I love the myHDF5 viewer, but there&#8217;s no good equivalent for Parquet and Zarr, and switching between different sites also gets annoying. So, I built a tool that provides a unified solution.<\/p>\n<p>It currently supports viewing several formats, including HDF5, Parquet, Zarr, Arrow, JSONL, NumPy, TFRecord, etc. I&#8217;m hoping to add more features\/formats depending on what people find useful!<\/p>\n<p>It&#8217;s free to use with no sign-up required. I&#8217;d love for people to try it out: <a href=\"https:\/\/viewkit.app\/\">https:\/\/viewkit.app\/<\/a><\/p>\n<p>Everything is loaded and parsed locally in your browser (WebAssembly + JS), so your data always remains on your machine. It&#8217;s also built to remain responsive on big files via efficient reading, caching, and prefetching. Traversing through data files actually feels faster than existing solutions like myHDF5 with simple caching\/prefetching strategies. It also supports some common data types that existing viewers don&#8217;t support (e.g. float16, complex numbers for HDF5).<\/p>\n<p>I&#8217;d appreciate any feedback (feel free to comment or send a message through the website). Looking forward to supporting additional features\/file formats that the community finds useful!<\/p>\n<\/div>\n<p><!-- SC_ON -->   submitted by   <a href=\"https:\/\/www.reddit.com\/user\/ayu055\"> \/u\/ayu055 <\/a> <br \/> <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1uxsw3b\/viewkit_an_interactive_tool_to_view_datasets\/\">[link]<\/a><\/span>   <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1uxsw3b\/viewkit_an_interactive_tool_to_view_datasets\/\">[comments]<\/a><\/span><\/p><div class='watch-action'><div class='watch-position align-right'><div class='action-like'><a class='lbg-style1 like-41752 jlk' href='javascript:void(0)' data-task='like' data-post_id='41752' data-nonce='9de69db8d5' rel='nofollow'><img class='wti-pixel' src='https:\/\/www.graviton.at\/letterswaplibrary\/wp-content\/plugins\/wti-like-post\/images\/pixel.gif' title='Like' \/><span class='lc-41752 lc'>0<\/span><\/a><\/div><\/div> <div class='status-41752 status align-right'><\/div><\/div><div class='wti-clear'><\/div>","protected":false},"excerpt":{"rendered":"<p>Hi all!
