The article discussed the way how to open LDF files in Excel using manual and automated techniques.
What is an LDF File in an MS SQL Server Database?
An LDF (Log Data File) is transactional information attached to SQL Server database files. It includes throughout history of the transaction and structures data in a secured path in the SQL Server. The LDF file can not open in any normal file format. It preserves the data uniqueness of the SQL database and for recovery of data and data rollback if required.
Challenges on How to Open LDF File in Excel
The main challenges to viewing, opening, and reading LDF files in Excel appear as follows:
- Both LDF and Excel have separate file extension consistency, i.e. LDF includes transactional log binary data while Excel opens in CSV and XLSX file format.
- LDF file needs SQL Server Management Studio (SSMS) to manage and read data in a simple form, which individuals can easily read and understand.
- LDF file format stores important transactional data and changes in the database, which requires a good understanding of SQL Server to read it correctly.
- SQL Admin Authorization is needed to access and read the LDF file MS SQL Server Database.
- Security and privacy are also an important aspect of LDF files, as contained inside the transaction file history and records of the user.
How to Open LDF File in Excel Manually
The manual way to open the LDF file in Excel in a
Method 1 Using SQL Server Management Studio (SSMS)
- Download, install, and launch the SQL Server Management Studio on your local machine.
- Now, connect with the SQL Server instance and proceed.
- Open and add the MDF File to the SQL Server Database, combined with the LDF file.
- Now, you can display LDF file records successfully after attaching them to logs.
- Logs to the server to open the LDF file.
Method 2 Using SQL Server Commands fn_dblog
Using the fn_dblog command, you can easily read the LDF file.
First, set up the database and check the LDF files associated with it.
SELECT name, recovery_model_desc, log_reuse_wait_desc, log_reuse_wait FROM sys.databases;Now, use fn_dblog to read the LDF files of the SQL Server database.
USE DB_DATA;
-- Check log information for a specific table
SELECT *
FROM fn_dblog(NULL, NULL);Using fn_dflog, you can filter the transaction log data to view particular operations (insert, delete, update) associated with a table or a certain period.
USE DB_DATA;
-- Filter log to show changes on a specific table
SELECT *
FROM fn_dblog(NULL, NULL)
WHERE AllocUnitName = 'dbo.name'; -- Replace with your table namefn_dblog can extract information on switches in a table.
USE DB_DATA;
-- Extract data changes from log (advanced)
SELECT [Transaction ID], [Begin Time], [Operation], [Transaction Name], [Description]
FROM fn_dblog(NULL, NULL)
WHERE Operation IN ('LOP_INSERT_ROWS', 'LOP_MODIFY_ROW', 'LOP_DELETE_ROWS')
AND AllocUnitName = 'dbo.name'; -- Replace with your table nameRestrictions of Manual Method
- Distorting the SQL LDF file in the absence of adequate technical knowledge and understanding may lead to data corruption of the file.
- Technical expertise in SQL commands is essential for the complete procedure.
- Fundamental knowledge of LDF files is required to be aware of the process.
- Adjacent modification can adversely affect LDF files, as they encompass significant transaction data.
Automated Tool How to Open LDF File in Excel
The world’s finest software application for opening and reading SQL LDF files is SysTools SQL Log Analyzer Tool. This software comprehensively scans and opens the LDF file in an SQL Server effectively and reliably. The software application works on all the MS SQL Server Database versions. It will analyze all the amendments in the SQL Server. This application comprehensively evaluates LDF files. The user can preview all log records using this program.
Steps to follow to view the LDF file –
- First, download the software, install and then run the software application on your local workstation.
- Click to open and add the LDF file from the System in the application.
- Now the user gets two modes to add an LDF file to the software application:
- Online DB Option – It enables the direct addition of LDF files from a SQL Server Database.
- Offline DB Option – For the Offline DB options, users need to manually select and open the LDF file without the SQL Server.
- Select the Export button to open its environments.
- Prefer a T-SQL query as you need it like INSERT, DELETE, UPDATE. Select and implement Date filters to the preferred query.
- The following Export option is SQL Server Database, SQL Server Compatible SQL Scripts, or CSV option to export the LDF files data into Excel.
- Now, select the file and location path to export LDF files in your system.
- Click on the Export button to choose the folder and publicize the .sql file in Excel.
Principal Characteristics of Suggested Software for Open LDF File
- All versions of MS SQL Server Database like 2022, 2019, 2017, 2016, 2014, 2012, 2008 R2, 2008, 2005 and 2000 LDF files.
- It completely analyzes the MS SQL transaction log (.ldf) file to detect significant changes in the SQL records.
- The software application enables the opening and previewing of transactional log activities in an MS SQL Server Database.
- The tool guides all Windows operating systems (11, 10, 8, 7, and XP) with both 32-bit and 64-bit versions.
- In online mode, the user can connect to the SQL Server database using login credentials to fetch and observe records and transactional logs. Users can view insert, delete, and update records.
- The software program allows users to maintain scanned transaction log files as STR files for forthcoming analysis.
- The tool facilitates the improvement of SQL Server data types like Datetime2, datetimeoffset, sql_variant, hierarchyid, geometry, and geography.
- The software does not require MS SQL Server installed in the computer system to review and forensic the MS SQL Server transactional log data files.
- The application provides sorting preferences to reorganize the items such as transaction, transaction time, table name, transaction name, and query.
- The tool enables a customizable filter to export only a particular transaction record after a complete analysis.
Conclusion
By reading this article, we discovered multiple techniques for how to open LDF files in Excel, employing both manual and automated approaches.
However, according to the expert’s opinion, they recommended automated software for opening LDF files in Excel because it is more efficient and reliable as compared to the manual method. This is because it saves a lot of time for a user.
