MySQL query result to PNG API

Code examples

These examples send the sample as multipart/form-data and save the returned bytes unchanged. Set TABLECONVERT_API_KEY in your environment.

curl --fail-with-body --max-time 40 \
  'https://api.tableconvert.com/v2/convert/mysql-to-png' \
  --header "Authorization: Bearer $TABLECONVERT_API_KEY" \
  --form-string 'data=+-----------+---------+--------+

| Dashboard | Healthy | 99.90  |

  --output 'mysql-to-png.png'

Request parameters

This source means copied MySQL terminal table output, not a live database connection. Border lines are removed and visible cell text is parsed.

Send one source: data, file, or url. The examples below use the source mode appropriate for this format.

Output options

Render extracted table values into a PNG image. The image shows a newly laid-out table and is not a screenshot of the source page.

This output format does not expose additional options.

Conversion rules

How the input is read

• Paste the bordered text table returned by the MySQL command-line client.
• No database host, password, query execution or connection is required or performed.
• Remove row-count messages, prompts and wrapped terminal output before conversion.
• Printed NULL values and numeric-looking cells are text; database column types are not available from the terminal rendering.

How the output is written

• Save the binary image response directly as a .png file.
• A raster image is useful for fixed display but does not retain editable cell structure.
• Review text width, row count and glyph rendering before using the image in a report.
• The public image endpoint has no theme option: unregistered theme fields are discarded, and the API uses its fixed table styling.

When to use this API

Responses and errors

Check the response before retrying. A new HTTP request is a new conversion and may use credits again.

Limits, billing and versions

Local previews accept up to 200 KB. The current API implementation allows one uploaded file up to 50 MiB, limits each multipart text field to 1 MiB, and gives v2 conversion tasks a 30-second deadline. Deployment limits may be stricter. Read the returned error before retrying; some parser or renderer failures return HTTP 500.

Live calls follow the API credit policy. Failed conversions are refunded; a completed conversion is not undone if the download connection later fails.

References and format specifications

Format references explain the underlying syntax. The conversion rules and samples above describe TableConvert’s implementation.
