Free online SQLITE to HTML converter

What the SQLite format is

SQLite is a self-contained relational database format stored in a file, usually with a .sqlite, .sqlite3, or .db extension. The extension is not definitive: SQLite databases can use other names, and .db can also identify unrelated database formats. An SQLite file can contain tables, indexes, views, triggers, foreign-key definitions, and other schema metadata.

Mobile applications, desktop programs, browsers, content-management systems, development tools, and embedded devices use SQLite because it needs no separate database server. Application exports, local records, caches, and small embedded datasets are common sources of SQLite files.

What the HTML format is

HTML is a text-based markup format interpreted by web browsers. A database export normally converts one or more tables or query results into HTML tables with headings and cell values. It does not preserve SQLite indexes, relationships, constraints, triggers, transactions, or SQL behavior as usable database features.

HTML is suitable for browser viewing, static reports, documentation, email attachments, and human-readable archives. CSS can control presentation, and a page can contain several tables, headings, links, and explanatory text, but editing the page does not update the source database.

How to convert SQLite to HTML

Use 101convert.com

1. Open the SQLite-to-HTML converter on 101convert.com.
2. Upload the .sqlite, .sqlite3, or .db file.
3. Select HTML as the output format and start the conversion.
4. Download the result and open it in a browser to check the exported tables and values.

The service can convert the file for free without installing database software. Do not upload databases containing confidential, personal, or regulated data unless the service’s handling and retention terms are acceptable.

Export a table or query with SQLite

The official SQLite command-line shell can produce an HTML table from a selected table or query. Start the shell with sqlite3 database.sqlite, then run:

.headers on
.mode html
.output records.html
SELECT id, name, created_at FROM records ORDER BY created_at;
.output stdout
.quit

Replace the query with the required table and columns. Run .tables to list tables and PRAGMA table_info(records); to inspect a table’s columns. Using an explicit column list avoids exporting unwanted fields and fixes the output order; use WHERE, ORDER BY, and joins when the report needs filtering, sorting, or related data.

The shell output is an HTML table fragment. To make a complete standalone page, place that output inside a document such as:

<!doctype html>
<html>
<head><meta charset="utf-8"><title>Records</title></head>
<body>
<!-- insert the exported table here -->
</body>
</html>

Generate a formatted page with Python

Python is useful when the page needs a title, multiple queries, custom formatting, or selected columns. The standard library can read SQLite and escape cell text before inserting it into HTML:

import html
import sqlite3

with sqlite3.connect("database.sqlite") as db, open("records.html", "w", encoding="utf-8") as out:
    rows = db.execute(
        "SELECT id, name, created_at FROM records ORDER BY id"
    )
    out.write("<!doctype html><meta charset='utf-8'>")
    out.write("<title>Records</title><table><tr>")
    out.write("".join(
        f"<th>{html.escape(column[0])}</th>"
        for column in rows.description
    ))
    out.write("</tr>")
    for row in rows:
        cells = []
        for value in row:
            text = "NULL" if value is None else str(value)
            cells.append(f"<td>{html.escape(text)}</td>")
        out.write("<tr>" + "".join(cells) + "</tr>")
    out.write("</table>")

For production exports, handle byte-valued BLOB columns separately instead of displaying their Python text representation. Convert timestamps, JSON, and numeric values according to the required display convention.

Quality and compatibility limits

NULL, dates, JSON, and BLOBs do not have dedicated HTML table types. Dates and JSON become text, while BLOBs may need decoding, separate files, or download links. HTML escaping is required for values containing characters such as <, >, and &; otherwise data can produce invalid markup or executable markup.

Large tables can create very large pages that load slowly and are difficult to search or print. Export only the required columns and rows, or split the data into several pages. HTML exports also omit permissions, indexes, triggers, foreign-key enforcement, transactions, and other database behavior. Keep the original SQLite file when the data must later be queried, updated, or re-imported without loss.

If the database is being copied while an application is using it, do not assume that copying only the main file is safe. A live SQLite database may also use database.sqlite-wal and database.sqlite-shm; close the application, use SQLite’s backup mechanism, or create a consistent snapshot before conversion.
