A row with an error cannot be published as it is. Content Uploader does not stop the whole file for it: the bad rows are listed, skipped, and everything else goes ahead. You fix the rows in your spreadsheet and upload again; rows that were already published show as unchanged.

The Errors list#

Select the Errors tile. If there are many, the list is grouped by message, so one mistake repeated in 300 rows is one line with the number of rows (4 rows with errors, grouped into 4 problems. Open a problem to see its rows.). Select a group to see its rows:

The Errors list: the tile with its count, then each problem with the number of rows, and the first problem opened to show its row
Four problems, one row each. The first is open: row 3 has an empty title.

Each row shows:

  • Row N: the row in your spreadsheet (row 1 is the header, so the first item is row 2; in a file read without a header row, the first item is row 1), so you can go straight to it.
  • Also: any other problems the same row has.
  • Show the row's values: every cell of that row, so you can see what was read.

A row's errors are named by the field: Title: …, Publish date: …, Status: …, Category: …, Record ID: ….

The four examples#

The example file 09-articles-with-problems.csv has one row for each common mistake:

Message The row The fix
Title: This field resolves to an empty value. HLJ-602, no title Fill the title.
Record ID: “HLJ-603” is used by an earlier row in this file. The second HLJ-603 Give each item its own ID. The first row with an ID counts.
Publish date: The resolved value must be a valid date. HLJ-604, next Tuesday-ish Write a date: 2026-09-23 09:00 (dates).
Status: The resolved value is not one of the destination choices. HLJ-606, Live Use a status the site offers: Published, Draft, Pending review, Private (status).

The other rows (here three: the good article, the first HLJ-603 and the one without a category) are new and publish normally, which is why the page says 4 rows with errors will be skipped. under the Publish button.

Fix and upload again#

  1. Correct the rows in the spreadsheet (the numbers tell you where).
  2. Upload the file again: you can upload the whole file again, or just the corrected rows with their IDs (partial updates).
  3. The rows already published are shown as unchanged, the corrected ones as new or updated.

You do not have to publish the good rows first: if you prefer, fix the errors and publish everything at once. If every row has an error, the Publish button says Nothing to publish and the page offers Upload the corrected file.

Errors that name the whole file#

Some problems are not about rows: a missing column stops the file before any row is read (This file doesn't match the configuration, see when a file's columns change), and a file that cannot be read says why on its page (the file cannot be read).

The messages#

The complete list of what a row can be told, with the reason for each, is in mapping errors and common mapping mistakes.
