Convert XLS to SQL in Batch — Export Excel Spreadsheets to SQL Database Dump

You have a stack of Excel spreadsheets that need to go into a relational database. Opening each XLS file, copying rows, and writing INSERT statements by hand is not realistic when you have dozens or hundreds of files. Total Excel Converter reads XLS files and exports them as SQL dumps — ready to import into MySQL, PostgreSQL, SQL Server, or any other database that accepts standard SQL. Here is what it does:

• Converts XLS to SQL with correct data types, quoting, and escaping for each cell value
• Processes hundreds of files in one batch — set options once, convert everything
• Uses column headers from the first row as SQL field names automatically
• Includes a command-line interface for scripting and scheduled tasks
• Works offline — spreadsheet data never leaves your PC
• 30-day free trial, no email or credit card required

Download Total Excel Converter and turn your XLS spreadsheets into SQL INSERT statements today.

 

XLS vs SQL: What Is the Difference?

XLS is the binary spreadsheet format used by Microsoft Excel 97–2003. It stores data in worksheets with rows, columns, cell formatting, formulas, and charts. XLS files are designed for human editing in a spreadsheet application — not for direct import into a database engine.

SQL (Structured Query Language) dump files contain plain-text commands — typically CREATE TABLE and INSERT INTO statements — that a database server executes to recreate tables and populate them with data. SQL files are the standard way to move structured data between database systems, back up table contents, or seed a new database.

The gap between the two formats is straightforward: XLS is built for spreadsheets, SQL is built for databases. When you need to load spreadsheet data into MySQL, PostgreSQL, MariaDB, SQL Server, or SQLite, converting XLS to SQL gives you a ready-to-import file that preserves every row and column from the original spreadsheet.

How to Convert XLS to SQL

• Step 1. Launch Total Excel Converter. The left panel shows a folder tree for quick navigation to your XLS files.
• Step 2. Browse to the folder containing your XLS spreadsheets. The file list in the center displays all supported files with size, date, and sheet count.
• Step 3. Check the XLS files you want to convert. Use Check All to select every file in the folder for batch processing.
• Step 4. Click SQL in the format toolbar at the top of the window.
• Step 5. Set the destination folder. Adjust SQL options in the conversion wizard: table name template, whether to use column headers as field names, character encoding, and which sheets to include.
• Step 6. Click Start. The converter processes all selected files and writes SQL dump files to the destination folder. Each XLS file produces one .sql file.

The entire batch completes in seconds, even for large file sets. Original XLS files remain unchanged.

Command-Line Conversion

Total Excel Converter includes a command-line interface for automated or scheduled conversion:

ExcelConverter.exe C:\Data\*.xls C:\Output\ -cSQL

This converts every XLS file in C:\Data\ to SQL and saves the results in C:\Output\. Additional flags control the output:

• -FirstRowAsHeader — use the first row of each sheet as SQL column names
• -TableName MyTable — set a custom table name in the SQL output
• -Sheet 1 — convert only the first sheet

Save the command in a .bat file and schedule it with Windows Task Scheduler to automate nightly data exports from Excel to your database.

Why Total Excel Converter?

Batch processing. Select hundreds of XLS files and convert them to SQL in one run. Processing an entire folder takes roughly the same time as converting a single file.

Accurate data transfer. Cell values are correctly quoted and escaped in the SQL output. Numeric fields stay numeric, text fields are properly enclosed in quotes, and NULL values are handled. No data is lost or corrupted during conversion.

Column headers to field names. The converter reads the first row of each spreadsheet and uses those values as SQL column names. No manual mapping required — the table structure mirrors the spreadsheet layout.

Built-in file viewer. Preview any spreadsheet before conversion to verify that the source data and layout are correct. Catch problems before they reach your database.

No cloud upload. All processing happens on your PC. Financial data, customer records, and proprietary business information never leave your machine.

20+ output formats. Beyond SQL, convert XLS to XLSX, CSV, PDF, XML, JSON, HTML, DBF, LaTeX, and more — all in the same tool.

Total Excel Converter Customer Reviews 2026

Rate ItRated 4.7/5 based on customer reviews

"We migrated a legacy inventory system that stored everything in Excel. Over 400 XLS files needed to go into MySQL. Total Excel Converter processed the entire batch in under two minutes. Column headers mapped to field names automatically, data types were correct, and the SQL imported without a single error. Saved me days of manual work."

Kevin Marsh Database Administrator

"Clients send us product catalogs as XLS files every week. I set up a .bat script that runs Total Excel Converter on a schedule, converts the new files to SQL, and feeds them into our PostgreSQL database. The whole pipeline runs unattended. The command-line interface made integration straightforward."

Samantha Reeves Web Developer

"Good tool for getting spreadsheet data into a database without writing custom import scripts. I use it to convert monthly sales reports from regional offices — each report is a separate XLS file with multiple sheets. The converter handles multi-sheet files well and produces clean SQL. Would appreciate an option to customize the CREATE TABLE data types, but the defaults work for most cases."
