"WP Post Corrector" is a plugin, helpful you to correct your post data. It contains mainly 3 modules. Bulk Upload (Insert Mass Post Data),
All I am doing with this is importing tags to my 200,000 posts. Works like a charm, I have a huge csv file with 2 columns (ID -> which matches my wp post ID, and post_tag -> which has my comma separated list of tags).
I did have to split the csv file up into manageable chunks of 5000 records per file, but uploading 30 files was still the easiest alternative i could find.
Worked for me!
I am not a fully trained programmer, But I am able to do and undo designing websites with the power of WordPress and its endless plugins and themes.(My NGO website)
Of all my efforts made in uploading bulk data to many WordPress using various plugin, I found the WP Post Corrector as the most SIMPLEST to use,VERSATILE for newbies, FRIENDLY User interface that generate easy to follow error reports, almost TROUBLE FREE and STRAIGHT FORWARD and above all it is FREE.
I wish the author release a version compatible to other operating system apart form MS Office excel- .CSV on windows. As for me, am very comfortable with WP Post Corrector using wndows 7 64bit, MS 2007 office.
Doesn't work, hasn't worked in over a year based on the reviews. Can not export, no idea if import works because the template is missing.
