Client-Side Only: Your tables are processed strictly in your browser. No data is stored or logged.

How to Use This Tool

Copy SQL CLI Output

Copy the ASCII table result printed in your terminal or database GUI query console.

Paste into Tool

Paste the output containing +---+ borders or pipe columns into the tool below.

Copy Markdown Table

The SQL borders are automatically stripped and converted into a standard GitHub Markdown table.

Worked Example

MySQL CLI Query Output

+----+------------------+---------+
| 1  | production_db    | online  |
| 2  | analytics_store  | synced  |
| 3  | redis_cache      | active  |
+----+------------------+---------+

Technical Specification & Mechanics

SQL CLI Result Parsing & Fixed-Width ASCII Border Stripping

Command-line SQL tools (MySQL, PostgreSQL psql, SQLite, SQL Server sqlcmd) format query outputs using fixed-width ASCII border art (+---+---+ and | column |). Our specialized parser strips bounding box lines, extracts column names from the header row, discards terminal status messages ("2 rows in set"), and outputs clean GitHub Flavored Markdown.

ASCII Border Filter: Removes decorative border rows like +--------+--------+ and +===+===+.

Fixed-Width Column Splitting: Accurately identifies column boundaries using delimiter lines.

Terminal Log Elimination: Discards execution time lines, row count summaries, and CLI prompt fragments.

NULL Value Representation: Translates SQL NULL tokens into clean blank table cells.

Markdown Table Pro Tips & Best Practices

Document Database Queries

DevOps

Copy query output straight from your terminal into this tool to document schema changes and migrations in GitHub PRs.

Right-Align Numeric Counts & IDs

Databases

Numeric database metrics (counts, timestamps, foreign keys) should be right-aligned (---:) for cleaner documentation.

Strip Terminal Prompts

Clean Data

Omit the mysql> or postgres=# prompt lines when copying to ensure pure tabular parsing.

Highlight Primary Keys with Code

Readability

Wrap ID column names in backticks (`user_id`) in your final Markdown output for clear technical contrast.

Common Pitfalls & How to Fix Them

Terminal summary lines appear as extra rows

Cause: Lines like "(3 rows)" or "Query OK" were copied along with query results.

Solution: Our engine filters standard CLI status messages automatically, or you can delete them in the visual editor.

Columns merged together

Cause: Query output was copied from a terminal that uses spaces instead of vertical pipes.

Solution: Enable pipe or box output in your database CLI (e.g. \pset border 2 in Postgres or -t in MySQL).

Platform & Markdown Flavor Compatibility

Platform / Specification	Support Status	Compatibility Notes
MySQL & MariaDB CLI	Supported	Detects standard ASCII tabular outputs.
PostgreSQL psql	Supported	Supports both border=1 and border=2 psql formats.
SQLite3 CLI	Supported	Parses .mode column and .mode box query results.
SQL Server sqlcmd	Supported	Parses dashed separator lines from MS SQL.

Frequently Asked Questions

Can I convert full SQL schema dumps or database manuals to Markdown?▼

This converter specifically parses ASCII tabular outputs from SQL query results into clean Markdown tables. If you need complete document conversions (such as turning technical specifications into PDF, Word DOCX, or HTML), visit our sister platform MDConverter (https://mdconverter.net).

Does this handle PostgreSQL table outputs without + borders?▼

Yes. Both MySQL-style bordered tables (+---+---+) and PostgreSQL-style column separator tables (----+----) are parsed accurately.

Can I paste comma-separated SQL dump rows?▼

Yes. If your query outputs CSV-formatted rows, our engine detects the commas and formats them into a table.

Does this execute SQL queries on my database?▼

No. This tool only formats text. You paste the terminal text output of a query you ran locally, and it converts it into a Markdown table.

Can I convert psql expanded display (\x) outputs?▼

Standard columnar tables are supported. For key-value vertical records, use our Markdown Table Transpose tool after converting.

How are SQL NULL values handled?▼

By default, SQL NULL tokens are cleaned to empty cells, or you can retain them as italicized *NULL* text.
