Google Docs API
Google Docs API
Google Docs API enables programmatic creation, reading, and editing of Google Docs — commonly used for report generation and template rendering.
Batched requests combine many edits in one call
Editing is mostly insert/replace — not structurally programmable like Word VBA
Enable Docs API; use documents.create to make new docs or batchUpdate to modify existing. Often paired with Drive API: copy a template, then batchUpdate to fill placeholders.

About this API
The core pattern with the Docs API is 'template + batchUpdate'. Developers prepare a template Google Doc with placeholders like {{name}} or {{date}}; the program uses the Drive API to copy the template into a new doc, then batchUpdate via the Docs API to replace placeholders with real values. This makes 'auto-generate a PDF/Doc from data' straightforward.
batchUpdate accepts an array of requests — insertText, replaceAllText, deleteContentRange, updateTextStyle, insertInlineImage, and more — executed in order. Each request has an index pointing into the document; later indexes are adjusted automatically as earlier requests change the structure. Complex layout (multi-column, charts, embedded objects) is poorly supported via API — for those, design the template in the UI and have the program only fill text fields.

FAQ
Can I convert to PDF?+
Yes — use Drive API's files.export with application/pdf to export a Doc.
How do I handle tables?+
You can create/modify/delete tables, but the syntax is verbose. Often easier to pre-create tables in the template and only fill cells.
Why isn't replaceAllText replacing my placeholder?+
Check whether Docs split the placeholder across multiple text runs (e.g. due to spell-check). Keep placeholders plain text without inline formatting.
