About this plugin
This WordPress plugin imports posts from CSV (Comma Separated Value) files into your
WordPress blog. It can prove extremely useful when you want to import a bunch
of posts from an Excel document or the like – simply export your document into
a CSV file and the plugin will take care of the rest.

Features
- Imports post title, body, excerpt, tags, date, categories etc.

write your posts)
- Columns in the CSV file can be in any order, provided that they have correct
headings
- Multi-language support

in order to keep up with changes to the core WordPress.
This importer writes directly to the database. It does not go through the internal
WordPress objects for creating posts etc. That may be an advantage to you (it will
be faster for large imports) but do be aware of any data integrity issues that may arrise.
Only UTF-8 encoding is supported, both with and without Byte Order Marks (BOM).

the normal WordPress channels.
Usage
Click on the CSV Importer link on your WordPress admin page, choose the
file you would like to import and click Import. The examples directory
inside the plugin’s directory contains several files that demonstrate
how to use the plugin. The best way to get started is to import one of
these files and look at the results.
CSV is a tabular format that consists of rows and columns. Each row in
a CSV file represents a post; each column identifies a piece of information
that comprises a post.
You can create new posts, or update existing posts by supplying the csv_post_id
field pointing to an existing post. When updating, all field names you provide
in the CSV file will be updated – even if blank – but fields you don’t list at
the head of the CSV file will be left intact.
Basic post information
- csv_post_id – optional, used to update an existing post.
- csv_post_title – title of the post
- csv_post_post – body of the post
- csv_post_type – post, page or a custom post type.
2, csv_post_type column supports custom post types.
Refer to the WordPress
documentation on custom post types for more info
on how to set up custom post types.
- csv_post_excerpt – post excerpt
- csv_post_categories – a comma separated list of category names or ids.
g. “EC > UK, Island”.
g. Animalia > Chordata > Mammalia
then they will all be created and the post assigned to the end of the chain.
g.
42 > Primates > Callitrichidae, where 42 is an
existing category id.
- csv_post_tags – a “quoted” comma separated list of tags.
- csv_post_date – most standard formats are supported.
For example, now, 11/16/2009 0:00, 1999-12-31 23:55:00, +1 week,
next Thursday, last year are all valid. For technical
details, consult PHP’s strtotime() function documentation.
Custom fields
Any column that doesn’t start with csv_ is considered to be a custom field
name. The data in that column will be imported as the custom fields value.
All custom fields must be unique. Multiple fields with the same name will be
updated to the same value if updating an existing post.
0 loading the same field name multiple times to an existing
post would create multiple custom fields.
General remarks
- WordPress pages don’t have categories or tags.
- Most columns are optional. Either csv_post_title, csv_post_post or
csv_post_excerpt are sufficient to create a post. If all of these
columns are empty in a row, the plugin will skip that row.
- The plugin will attempt to reuse existing categories or tags; if an
existing category or tag cannot be found, the plugin will create it.
- To specify a category that has a greater than sign (>) in the name, use
the HTML entity >
Advanced usage
- csv_post_author – numeric user id or login name. If not specified or
user does not exist, the plugin will assign the posts to the user
performing the import.
- csv_post_slug – post slug used in permalinks.
- csv_post_parent – post parent id.
Custom taxonomies
0
php file or
by using a 3rd party plugin, csv_ctax_(taxonomy name) columns can be
used to assign imported data to the taxonomies.
Non-hierarchical taxonomies
The syntax for non-hierarchical taxonomies is straightforward and is essentially
the same as the csv_post_tags syntax.
Hierarchical taxonomies
The syntax for hierarchical taxonomies is more complicated. Each hierarchical
taxonomy field is a tiny two-column CSV file, where the order of columns
matters. The first column contains the name of the parent term and the second
column contains the name of the child term. Top level terms have to be preceded
either by an empty string or a 0 (zero).
csv file included with the plugin
illustrates custom taxonomy support. To see how it works, make sure to set up
php.
Make sure that the quotation marks used as text delimiters in csv_ctax_
columns are regular ASCII double quotes, not typographical quotes like “
(U+201C) and ” (U+201D).
Comments
1
An example file with comments is included in the examples directory.
In short, comments can be imported along with posts by specifying columns
such as csv_comment_*_author, csv_comment_*_content etc, where * is
a comment ID number. This ID doesn’t go into WordPress. It is only there
to have the connection information in the CSV file.
