Looking For Feedback On A Workflow I Built"},"content":{"rendered":"<p><!-- SC_OFF --><\/p>\n<div class=\"md\">\n<p>I&#8217;ve been working on a mixed-methods research platform, and one thing that kept coming up from users was the pain of cleaning datasets before they could even start analysing them.<\/p>\n<p>Most people were either writing Python\/R scripts or doing it manually in Excel. Both of which break the workflow when you just want to get to the analysis.<\/p>\n<p>So I built a data cleaning module directly into the analysis tool. It handles the usual stuff:<\/p>\n<ul>\n<li>Duplicate removal (exact match or by specific columns)<\/li>\n<li>Missing value handling (drop rows, fill with mean\/median\/mode\/custom value, forward\/backward fill)<\/li>\n<li>Outlier detection (IQR and Z-score methods)<\/li>\n<li>String cleaning (trim, case conversion)<\/li>\n<li>Type conversion<\/li>\n<li>Find &amp; replace (with regex)<\/li>\n<li>Row filtering by conditions<\/li>\n<\/ul>\n<p>Each operation shows a preview with before\/after diffs so you can review changes row by row before applying. There&#8217;s also inline cell editing for quick manual fixes and one-click undo.<\/p>\n<p>Curious how others approach this:<\/p>\n<ul>\n<li>Do you clean data in a separate tool or prefer it integrated into your analysis workflow?<\/li>\n<li>What operations do you find yourself doing most often?<\/li>\n<li>Anything obvious I&#8217;m missing?<\/li>\n<\/ul>\n<p>Happy to share a link if anyone wants to try it out. Works with CSV, Excel, and SPSS files.<\/p>\n<\/div>\n<p><!-- SC_ON -->   submitted by   <a href=\"https:\/\/www.reddit.com\/user\/Sensitive-Corgi-379\"> \/u\/Sensitive-Corgi-379 <\/a> <br \/> <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1rpx735\/how_do_you_handle_data_cleaning_before_analysis\/\">[link]<\/a><\/span>   <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1rpx735\/how_do_you_handle_data_cleaning_before_analysis\/\">[comments]<\/a><\/span><\/p><div class='watch-action'><div class='watch-position align-right'><div class='action-like'><a class='lbg-style1 like-39538 jlk' href='javascript:void(0)' data-task='like' data-post_id='39538' data-nonce='65e0e39b87' 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-39538 lc'>0<\/span><\/a><\/div><\/div> <div class='status-39538 status align-right'><\/div><\/div><div class='wti-clear'><\/div>","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve been working on a mixed-methods research platform, and one thing that kept coming up from users&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[85],"tags":[],"class_list":["post-39538","post","type-post","status-publish","format-standard","hentry","category-datatards","wpcat-85-id"],"_links":{"self":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts\/39538","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/comments?post=39538"}],"version-history":[{"count":0,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts\/39538\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/media?parent=39538"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/categories?post=39538"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/tags?post=39538"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
