FORMAT: 1A HOST: https://www.ethercalc.org/ # EtherCalc API for real-time collaborative spreadsheets. * Overview: http://ethercalc.net/ * δΈ­ζ–‡η‰ˆ: http://ethercalc.tw/ Note: When using `curl`, please make sure to `--data-binary` instead of `--data`. For example: ```bash curl -X PUT -H 'Content-Type: text/x-socialcalc' \ --data-binary @example.sc http://127.0.0.1:8000/_/example ``` # Index [/_] ## Create Page [POST] Takes a JSON structure with `room` and `snapshot` fields. Replaces the page with a serialization in Socialtext save format. If `room` is not specified, returns a new page. + Request (application/json) ```json { "room": "test" , "snapshot": "..." } ``` + Response 201 + Headers ``` Location: /_/test ``` ## Create from CSV [POST] Takes a CSV structure that contains the new spreadsheet's content. + Request (text/csv) + Response 201 ## Create from SocialCalc [POST] Takes a SocialCalc serialization format that contains the new spreadsheet's content. + Request (text/x-socialcalc) + Response 201 ## Create from Excel XML [POST] Takes a Excel XML file that contains the new spreadsheet's content. + Request (application/vnd.openxmlformats-officedocument.spreadsheetml.sheet) + Response 201 # Page [/_/{id}] ## Page Content [GET] Fetch the page as a serialization in SocialCalc save format. + Response 200 (text/x-socialcalc) ## Overwrite with CSV [PUT] Replace the page with a serialization in CSV format. + Request (text/csv) + Response 200 ## Overwrite with SocialCalc [PUT] Replace the page with a serialization in SocialCalc save format. + Request (text/x-socialcalc) + Response 200 ## Overwrite with Excel XML [PUT] Replace the page with a serialization in Excel XML format. + Request (application/vnd.openxmlformats-officedocument.spreadsheetml.sheet) + Response 200 ## Post Commands [POST] Takes a JSON structure with a `command` field (either as a string or an array of strings), or a plain-text command string. Runs one or more commands specified in the `command` field. To find out which command corresponds to which spreadsheet actions, perform the actions on the web interface and check the _Audit_ tab for the recorded commands. + Request (application/json) + Response 202 ```json {"command": "..."} ``` ## Append Rows [POST] Takes a CSV structure that contains fields to be appended to the first column after the last row. + Parameters + row (optional, integer) ... If specified, insert and paste on the specified row instead of the last. + Request (text/csv) + Response 200 ## Delete Room [DELETE] Deletes a room from the database + Response 201 OK # Point-in-Time Restore [/_/{id}/pitr-restore] ## Restore a hosted room [POST] Restores the complete SQLite-backed Durable Object for one room to a Cloudflare PITR bookmark from approximately the previous 30 days. This recovers the snapshot, commands, audit/chat state, cell metadata, and alarms together. Local Miniflare and standalone workerd do not retain PITR history and return `501`. The route requires the deployment operator token: ```text Authorization: Bearer ``` If `ETHERCALC_MIGRATE_TOKEN` is unset, the route is hidden with `404`. A missing or incorrect bearer returns `401`. Supply exactly one target. `at` accepts a positive millisecond epoch or an ISO-8601 timestamp. `dryRun` resolves and returns the target bookmark without scheduling a restore: + Request (application/json) ```json { "at": "2026-07-10T00:00:00.000Z", "dryRun": true } ``` + Response 200 (application/json) ```json { "dryRun": true, "bookmark": "0000007b-..." } ``` Apply either the resolved bookmark or a previously returned undo bookmark: + Request (application/json) ```json { "bookmark": "0000007b-..." } ``` + Response 200 (application/json) ```json { "restored": true, "bookmark": "0000007b-...", "undoBookmark": "0000009d-...", "exists": true, "updatedAt": 1783641600000 } ``` `exists` is `false` when the restored point predates room creation; `updatedAt` is then omitted. To undo a restore, submit the returned `undoBookmark` as `bookmark`. A freshly created room has no PITR history until Cloudflare's change log catches up (about a minute in practice). Until then, timestamp dry-runs return `400 PITR target is unavailable`; poll the dry-run before scheduling a real restore. Invalid requests or unavailable/expired targets return `400`. An unsupported deployment returns `501`. A dispatch failure before the restore is accepted returns `502` as plain text β€” nothing was scheduled. Once the restore is accepted, the rewind is already armed, so later failures return JSON that keeps the reverse handle: + Response 500 (application/json) ```json { "accepted": true, "bookmark": "0000007b-...", "undoBookmark": "0000009d-...", "error": "PITR restore did not restart the room" } ``` Finalization failures after a confirmed restart use the same shape with status `502` and `"error": "PITR restore finalization failed"`. In both cases retain `undoBookmark`: the restore may have applied (or still apply), and submitting `undoBookmark` reverses it. # Page Cells [/_/{id}/cells] ## GET Returns a JSON representation of all defined cells in the page. + Response 200 (application/json) # Cell Value [/_/{id}/cells/{coord}] ## GET Returns a JSON representation of a single cell in the page. + Response 200 (application/json) # HTML Export [/{id}.html] ## GET Returns a HTML rendering of the page.
