HOW IT WORKS

Three steps. That's it.

Design the template

Use the PowerPoint you already have. Drop placeholders like {name} where values should change.

Hand over the data

Paste JSON in the web UI, or call POST /v1/jobs with an API key.

Get the file

PPTX or PDF, delivered via a download link.

BUILT-IN POWER

Beyond simple substitution

Loops, conditions, dynamic images, tables — logic you'd normally hand-code, all in a single placeholder.

{name}

Variable substitution

Text / number / date with type, format, and default value — all in one line: {price|number|#,###|0}.

{@items}

Array iteration

Expand a slide or table row per array element. Pagination supported.

{#user.isPaid}

Conditional rendering

Slides and rows visible only when a JS expression evaluates true.

{$photoUrl}

Dynamic images

Drop a remote URL or base64 string straight into an image box. Product photos, QR codes, done.
