Upload & Merge CSV Data with Images to Notion Database

CSV2Notion Neo

An advance method to upload & merge *.csv or *.json files with images to Notion database.

Core Features

Advantages over native import

• Merge CSV or JSON with the existing database, using the first column as a key to combine existing rows
• Choose column types manually instead of letting Notion detecting them automatically
• Link or create new entries in relation columns based on their values automatically
• Easily upload files into the designated "Files & Media" column
• Assign a icon for each row for quick identification
• Set a cover or embed an image for each row to enhance visual representation
• Upload image files for covers or icons
• Apply validation options for input data to ensure accuracy

Disadvantages over native import

• Importing each row separately might lead to slower speed
  • To address this, utilise multithreaded upload

Background

Originally, we developed csv2notion to address the lack of advanced importing support for *.csv files in Notion. We took inspiration from Airtable’s CSV import extension.

CSV2Notion Neo was created as a spin-off project to address inactivity in the original repository and maintain compatibility with Notion. As Notion changes or updates its backend API periodically, we aim to fix, update and add new features to the tool in a timely manner. Any dependent tools or project that relied on csv2notion, can use our CSV2Notion Neo tool interchangeably requiring additional augments.

macOS Release

Privacy & Security

For macOS, you have the option of two distinct releases: one packaged within a .zip archive and the other in a .pkg format. Navigate to the Privacy & Security settings and set your preference to App Store and identified developers.

Utilise the CSV2Notion Neo.pkg installer to install the command-line binary into your system. Upon completion, find the installed binary csv2notion_neo located within /usr/local/bin. To uninstall, you can utalise this terminal command.

sudo rm /usr/local/bin/csv2notion_neo

Prerequisite

You must pass a single *.csv file for upload. The CSV file must contain at least 2 rows. The first row will be used as a header.

Optionally you can provide a URL to an existing Notion database with the --url option; if not provided, the tool will create a new database named after the CSV file. The URL must link to a database view, not a page.

Obtaining Database URL

Obtaining Workspace Name

1. To see your Workspace name go to Settings & members at the top of the left sidebar. In the window that pops up, click on the Settings tab.
2. If your Workspace name is Acme Inc., you are required to provide --workspace "Acme Inc." as such.

The tool also requires you to provide a token_v2 cookie for the Notion website through --token option.

1. Login to your Notion account via a web browser.
2. Find and copy the entire token_v2 value including v02%3Auser_token_or_cookies% from your Notion session.

Obtaining Notion Session Token (Safari)

Enable Web Inspector

• If you don’t see the Develop menu in the menu bar, choose Safari, Settings, click Advanced, then select “Show features for web developers”.
• Press ⌥ + ⌘ + i to show Web Inspector

Obtaining Notion Session Token (Brave, Chrome or Edge)

Go to Setting, Privacy and security

Important notice. token_v2 cookie provides complete access to your Notion account. Handle it with caution.

Upload Speed

Due to API limitations, the upload is performed one row at a time. To speed things up, this tool uses multiple parallel threads. Use the --max-threads option to control how fast it will go. Try not to set it too high to avoid rate limiting by the Notion server.

Duplicate CSV Columns

Notion does not allow the database to have multiple columns with the same name. Therefore CSV columns will be treated as unique. Only the last column will be used if CSV has multiple columns with the same name. If you want the program to stop if it finds duplicate columns, use the --fail-on-duplicate-csv-columns flag.

Missing Columns

If a CSV file has columns absent from Notion DB, they will be ignored by default. Use the --add-missing-columns flag if you want the tool to add missing columns into Notion DB. Use the --fail-on-missing-columns flag if you want the program to stop if it finds a column mismatch.

Column Types

By default, the tool will try to guess column types based on their content. Alternatively, you can provide a comma-separated list of column types with the --column-types option when creating a new database or adding new columns with the --add-missing-columns flag. Since the first column in Notion DB is always text, the tool will use the list to set types for the rest of the columns.

By default, new options for select and multi_select columns are added with default (gray) color. If you want the tool to randomize colors for new options, use the --randomize-select-colors flag.

Some column types do not support assigning value to them because the database generates their content automatically. Currently these types include created_by, last_edited_by, rollup and formula. If you want the program to stop if it finds such columns in the database, use the --fail-on-unsettable-columns flag.

If the tool cannot convert the column value type properly, it will replace it with an empty string. If you want to make sure all values are correctly converted, use the --fail-on-conversion-error flag, which will stop execution in case of a conversion error.

The table below describes available codes for --column-types and what values are supported by each column type:

Support Table

Basic
Text	text	string	❌
Number	number	numerical	❌

Last edited by	last_edited_by	---	---

Merging

By default, the tool will add rows to the existing Notion DB. To merge CSV rows with the Notion database, use the --merge flag. The first column of CSV and Notion DB will be used as a key to update existing rows with new values. CSV rows that didn't have a match in Notion DB will be added as new.

Since the tool treats rows as unique during merge based on the key column, it will use first found rows with a unique key. To avoid this ambiguity, you might want to validate duplicate row keys with the --fail-on-duplicates flag. It will check both CSV and target Notion DB before the merge.

If you want only select columns to be updated, use the --merge-only-column option.

If you don't want the tool to add any new rows not already present in the Notion DB during merge, use the --merge-skip-new flag.

Relation Columns

Notion database has a relation column type, which allows you to link together entries from different databases. The tool will try to match column data with keys from a linked database.

By default, it will match with the first found row; it will add nothing if it cannot find the match. Use the --add-missing-relations flag if you want the tool to create new entries in the linked DB if no match is found. Use the --fail-on-conversion-error flag if you want the program to stop if no match is found.

You can also use Notion URLs in columns of this type, and they must belong to the linked DB. The tool will not be able to add missing entries for URLs if you use the --add-missing-columns flag.

Since the tool treats rows in the linked DB as unique you can prevent ambiguous matching with the --fail-on-relation-duplicates flag. It will check linked DB for duplicate keys and stop the executions if it finds any.

If linked DB is not accessible (linked DB is deleted or your account doesn't have access to it), columns that point to it will be ignored. If you prefer the program to stop in this case, use the --fail-on-inaccessible-relations flag.

Cover Image & Embedded Image

The tool allows you to add an image to each row with the --image-column option. It will use one column from CSV as a data source for the image. It can be either a URL or a file name. The file name must be either an absolute path or a path relative to the CSV file. The tool will upload the file to the Notion server.

By default, the tool will embed an image inside the row page. If you want it to use the image as a page cover, then set the --image-column-mode option to cover.

Column specified with the --image-column option will not be treated as a regular column by default. If you want it to appear in Notion DB, use the --image-column-keep flag.

To add custom caption to image block uploaded with --image-column-mode set to block, use --image-caption-column option. To also keep the caption as a Notion DB column, use --image-caption-column-keep flag.

Icons

The tool allows you to add an icon to each row with the --icon-column option. The behavior is the same as with --image-column; the only difference is that you can use URL, file name, or single emoji.

To also treat --icon-column as a regular column, use --icon-column-keep flag, similar to --image-column-keep.

If you want to set the same icon for each row, use the --default-icon option. If both --icon-column and --default-icon are present, the default icon is used if the row doesn't have anything in the icon column.

Mandatory Columns

If you want to ensure that specific columns always have value and are not allowed to be empty, then use the --mandatory-column option. The program execution will stop if validation fails.
