CSV Import Tools in Lockbox 2.0

What is a CSV Import?

A CSV (Comma-Separated Values) file is a simple text format that organizes data into rows and columns, making it an accessible and widely used format for data exchange. Within a laboratory, CSV import tools enable users to upload large datasets quickly and efficiently into a LIMS from instruments and other data sources. By mapping CSV columns to Lockbox fields, labs can quickly and accurately enter critical data such as sample information, test results, and inventory details into the system. This process eliminates the need for manual data entry, reduces errors, saves time, and ensures consistency in laboratory workflows.

Steps for Importing Data Using a CSV File

Importing data into Lockbox using a CSV file involves several straightforward steps. Simple CSV imports with hundreds of records can be completed in a few minutes. With additional configuration, Lockbox can accommodate an import of up to 10,000 records, processed asynchronously in the background while the user completes other work. First, the data is prepared, ensuring the file format and structure align with Lockbox LIMS requirements. Next, users map the CSV columns to specific fields within the system, ensuring all data aligns accurately. Once the mapping is complete, Lockbox will retain the information and automatically recognize and import the CSV file for future imports. Finally, Lockbox validates the data to catch any errors or inconsistencies. Common errors, such as missing values or incorrect formats, can be addressed during this validation step. This systematic approach ensures that the data is accurate, reliable, and ready for use in laboratory operations.

Key Features of the Enhanced Lockbox CSV Import Tool

Lockbox offers advanced features for CSV imports, making the process more efficient and user-friendly. Customizable field mapping allows users to align incoming data structure with their Lockbox configuration. Built-in error detection and validation ensure data integrity by flagging issues such as missing values or incorrect formats. Automation capabilities facilitate recurring imports, saving time for labs that frequently handle similar datasets and large sample sizes. Additionally, CSV import tools often support integration with external software or instruments, enabling seamless data exchange across platforms and improving laboratory efficiency.

• User-Friendly Setup: Easily create and configure a new CSV import template, called an Import Definition, with a few clicks.
• Customizable Labels: Add descriptive labels to organize and identify Import Definitions (e.g., “Sample Import”). Add a unique, descriptive label for each Import Definition Column associated with the Import Definition (e.g., “Sample Name”). This label is shown to the user during import, helping them correlate each Import Definition Column with the correct column in the CSV file.

• Flexible File Formats: Supports both comma-separated and semicolon-separated CSV files to accommodate users in all countries.
• Header Detection: Option to recognize column headers for dynamic field mapping, ensuring flexibility in column order.
• Target Object Selection: Specify the API name of the object to which records should be imported (e.g., samples or inventory).
• Import Types: Choose to add new records, update existing records, or perform both actions in one import.
• Optional Column: By default, all columns are required, but the user can set columns as optional, allowing more flexibility in data handling. 
• Insert Null Values: This option designates whether blank or null values from the CSV overwrite existing data in the system, ensuring that missing values are handled appropriately.
• Is Key for Updates: Indicates whether the column will be used to match existing records for updating. This is crucial for updating records instead of creating new ones. 
• Parent Column Name or Number: Used when importing child records that need to be associated with a parent object (e.g., linking Samples to a Project). It helps maintain the hierarchy in the data structure.
• Skip Row if Equals: Allows users to skip rows in the CSV based on a specific value (e.g., skip all rows with a blank value or a specific identifier). This feature helps streamline the import process by excluding unwanted data or fields that may have been inserted by instrumentation.
• Default Value: This provides the option to insert a default value for a column if no value is present in the CSV. This ensures consistency and avoids errors due to missing data.
• Advanced Field Mapping: Includes options to use the Well ID and Plate ID as unique keys for sample matching or to specify parent-child relationships for linked data (e.g., Samples to Projects).
• Row Skipping: Designates a number of rows with unnecessary information to skip before the actual data begins (e.g., metadata or instructions).

• File Retention: Option to save the imported CSV file for future reference or audits.

• Error Handling Options: Users can define what Lockbox should do if errors are encountered. Lockbox can abort an import with unmatched lookup errors, import with warnings, or ignore invalid lookup values.
• Validation and Feedback: Built-in error detection provides detailed messages for troubleshooting, ensuring data accuracy.
