How to Migrate Parquet to Access Database in Windows? Best Ways Explained

Different organizations use different database systems and file formats to manage and store data, like Parquet file format, Access Database, or SQL Server database. Now, in a few demanding situations, users need to migrate Parquet to Access Database as per the needs. Now, this does seem like a complex process and requires complete user’s expertise to carry out the process. However, to ease the process for users and further explain the reasons and the challenges, we will be discussing all the crucial aspects of this migration process.

Beginning with understanding a little more about the two file formats, and then finding the best ways for this migration. 

Learning More About Parquet and ACCDB/MDB Files

When working with the Parquet file format, here are a few things a user must know about the file.

• Parquet file format basically stores the data in a column-by-column format, unlike other data storage file formats, which use row-by-row format. 
• The Parquet file format is generally used for storing and managing large datasets for efficient data management and analysis. 
• With the .parquet file format, the major benefit the users get is that this file format supports high compression, minimizing the storage costs and file sizes. 

Moving on to the Access database file formats, let’s see how they are different and why it is more efficient to migrate Parquet to Access Database for given situations. Let’s take a closer look at Access database files. 

• The Access database generally stores the data in relational table format. 
• Access Database generally uses two file formats, MDB and ACCDB, respectively. The MDB file format was introduced for the older versions of the Access database, whereas the ACCDB was introduced for the newer versions (after 2007). 
• This file format allows users to effectively create reports, forms, and queries, without requiring much of technical expertise. 

We will now take a look at the situations that require the users to convert .parquet file to ACCDB or MDB files.

Reasons for Parquet File Transfer to Access Database

Here are some of the common reasons that require users to migrate Parquet to Access Database:

• One of the common reasons for users to move the .parquet file to Access database as it offers a simple and easy user interface to manage data. 
• Another major benefit of this migration is that Athe ccess database is simpler to integrate with general reporting tools like Excel. 
• When we work with MDB or ACCDB databases, the advantage we get is that these database files are easily accessible offline. This profits users to access or work on the files without requiring an internet connection. 

These are a few of the reasons that allows users to carry out their desired tasks and operations. We will now take a look at the best ways that will help the users to export Parquet file to Access Database in a convenient way. 

How to Migrate Parquet to Access Database Easily?

We will now be discussing the ways that will allow users to carry out the migration easily and effectively. Here are the methods we will be discussing:

1. By converting .parquet to CSV first and then importing CSV to Access Database.
2. By using a Professional Solution for parquet file transfer to MDB/ACCDB database.

Let’s move to understanding the steps of the first method. 

Method 1: Convert to CSV and Then Import to ACCDB/MDB

1. Use the given command to carry out the conversion process. 

import pandas as pd
df = pd.read_parquet("input.parquet")
df.to_csv("output.csv", index=False)

1. Next, open Microsoft Access and proceed to create a new database file. 
2. In the External data menu, select the Text File option. 
3. Browse the converted CSV file, then continue with the Import wizard to finish the Parquet to Access import. 

This method is quite simple if you look for a simple migration. However, there are certain limitations with this one. Here are some of them:

• The major impact of the conversion using this way is that the data types within the .parquet files are changed to plain texts further affecting the consistency of the files. It might also lead to risks like loss of schema and data. 
• We are well aware that the .parquet files are used to store large datasets, however, transforming them to CSV file format also results in larger file size as CSV files are text-based. 
• Another drawback of using this method is that the Parquet files usually contain metadata, and CSV file format doesn’t entirely support metadata.

With these issues, users might not risk using the manual way for this process. Let’s now move to the automated solution to look how that helps. 

Method 2: Using Professional Tool to Migrate Parquet to Access Database

In this method, we will be using a professional tool to make the entire transfer process easier. The utility we suggest is using the SysTools Parquet File Converter Tool, a solution designed to easily change Parquet to ACCDB/MDB database without affecting its data integrity.

We will now take a look at the steps of using this tool for precise results.

1. Install and run the suggested software. Click on Add Files to load .parquet files to the software.
2. After adding the files, click on the Next Button.
3. Next, choose the required file format from the resultant file format options.
4. Browse the destination path to save the transformed file to the desired location.
5. Click on the Export button for Parquet to ACCDB/MDB transfer.

With these easy-to-follow steps, users can migrate the data without compromising the data structure and originality. This utility allows users to carry out the process without encountering the limitations that were in the manual solution. 

Conclusion

With this thorough write-up, we have learned thoroughly about the migrate Parquet to Access Database. We have also learned about the reasons this migration is required, and further, the best ways that help users with this transfer process.
