# Bulk scheduling with CSV: validate every row before any import

A portable CSV staging contract for Arabic text, UTF-8, media URLs, time zones, row validation, dry runs, and rollback—without promising an unsupported importer.

**Answer first:** Naasher does **not currently promise a general CSV import path**. Use CSV as a portable, validated staging file for migration or controlled tooling only. Preserve UTF-8, quote multiline Arabic correctly, normalize time into UTC with its source zone, verify provider-reachable media, dry-run every row, and keep a rollback map before any scheduler accepts the batch.

## Separate portable columns from provider-specific behavior

A durable CSV describes intent without pretending every network shares one publishing model.

__Portable and nonportable scheduling fields__

| ------------------------- | ------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- |
| ClassPortable identity    | Examplesclient\_row\_id, workspace\_ref, account\_ref, provider                       | RuleUse stable references; resolve and display the exact destination in dry run |
| ClassPortable content     | Examplesbody, alt\_text, media\_url, scheduled\_at\_utc, source\_timezone             | RuleUTF-8 text with explicit quoting and time semantics                         |
| ClassCampaign context     | Examplescampaign\_ref, language, approved\_version, utm\_source, utm\_campaign        | RuleRetain for review; never silently rewrite approved links                    |
| ClassProvider-specific    | Examplesprivacy, first comment, poll choices, location, thread position               | RuleValidate through an explicit adapter; blank does not mean supported default |
| ClassNonportable evidence | Examplesapproval history, provider IDs, media binaries, comments, analytics snapshots | RuleMove separately with provenance; do not flatten into one cell               |

Use a unique `client_row_id` so dry-run errors, approval, scheduling results, and rollback decisions refer to the same source row. Do not use row number as identity; sorting changes it.

## Preserve Arabic, emoji, and line breaks

Save UTF-8\. A UTF-8 BOM can help spreadsheet software recognize Arabic, but the receiving parser must tolerate and strip it from the first header. Record the delimiter. The Arabic comma `،` belongs to content and is not the same as the ASCII CSV delimiter `,`.

Quote any field that contains a comma, Arabic comma plus surrounding CSV punctuation, double quote, or line break. Escape a literal double quote by doubling it. Keep hashtags and emoji as Unicode; do not replace them with lossy legacy encodings. Normalize line endings at ingestion while preserving intentional line breaks inside the quoted body.

```csv
client_row_id,account_ref,body,scheduled_at_utc,source_timezone,media_url
launch-017,riyadh-linkedin,"أطلقنا النسخة الجديدة، اليوم 🚀
التفاصيل: https://example.com/release",2026-09-03T06:00:00Z,Asia/Riyadh,https://media.example.com/launch-017.jpg

```

Check Unicode normalization for visually similar Arabic sequences and keep a test fixture containing Arabic-Indic and Western digits, hashtags, emoji, a quoted phrase, a URL with UTM parameters, and a multiline caption. Review the rendered preview; byte-valid text can still be directionally confusing.

## Convert time with a named zone

For the worked fixture above, `2026-09-03 09:00` in `Asia/Riyadh` maps to `2026-09-03T06:00:00Z`. Calculate this with a current time-zone library; do not hard-code a permanent offset rule. Store both the canonical UTC instant and the source IANA zone, and show the approver the local date and time again.

Reject ambiguous local input such as `09/03/26 9:00`, a missing zone, or a locale-dependent spreadsheet date serial. Define the accepted ISO format, then parse strictly.

## Make media reachable and auditable

A media URL must use HTTPS, return the intended file rather than an HTML login page, expose the right content type, and remain reachable through the provider's upload and processing window. A URL that works in the operator's signed-in browser may fail from a provider worker.

Prefer the product's supported upload flow when available. Otherwise use a controlled, time-bounded URL with enough lifetime, no personal query token in logs, and a retained asset digest. Validate dimensions, size, codec, alt text, and rights per target before scheduling.

## Run a deterministic dry run

The dry run must make no external publishing mutation. For every row it should:

1. Parse encoding, header, delimiter, quotes, and required fields.
2. Resolve workspace and account allowlists without printing credentials.
3. Validate UTC and display the source-zone interpretation.
4. Validate text, link domains, media reachability, and target capabilities.
5. Match the exact approved version and flag edits.
6. Produce `ready`, `blocked`, or `needs review` with reason codes.

Do not schedule the valid subset silently when blocked rows share one approval decision. The operator must choose whether partial acceptance is allowed and record that choice.

## Use validation fixtures before customer data

Maintain fixtures for a valid Arabic multiline row, UTF-8 BOM, missing account, duplicate `client_row_id`, bad quote, expired media URL, unsupported provider column, invalid UTC, repeated source row, and edited approved link. The expected result should include a stable error code and no write.

Then test one low-risk row end to end. Require a local schedule identifier, per-target provider outcome, and remote visible result. A created local row is not proof of publication.

## Plan rollback before importing

Keep an immutable source file digest, import/batch ID, row-to-local-ID map, authorizer, and timestamp. Rollback must distinguish unscheduled records, queued jobs, provider-accepted requests, and live posts. Cancel locally only when still safe; do not assume deleting a scheduler record removes a provider post.

If a batch is partially successful, stop the importer, reconcile every target, and retry only the confirmed failed subset. Follow the [publishing incident runbook](/en/guides/publishing-incidents) for late success and uncertain outcomes, and the [migration runbook](/en/guides/migration-runbook) before disabling the old scheduler.

## Naasher product limit and safe next step

Naasher supports composing and scheduling through its current UI and scoped API/MCP surfaces on eligible plans, but it does **not** currently advertise a general customer CSV importer. Do not build a customer migration promise around an internal script, a file shape from another product, or this guide.

Use this contract to clean and review data, then recreate approved items through documented product paths unless the live workspace exposes a supported importer with its own schema, validation, and rollback contract. For Arabic preview details, use the [mixed-direction guide](/en/guides/arabic-mixed-direction); for agent-generated batches, require the controls in [AI agent publishing safety](/en/guides/ai-agent-publishing-safety).

## Release checklist

- Encoding and delimiter are explicit; BOM behavior is tested.
- Multiline Arabic, commas, hashtags, emoji, quotes, digits, and URLs round-trip.
- Every account resolves to an allowed destination.
- UTC and the named source zone agree in the preview.
- Media remains provider-reachable and matches target constraints.
- Dry run produces stable row decisions without writes.
- Approval binds the exact file digest and accepted rows.
- Rollback maps every row to local and remote state.
- Unsupported columns and missing evidence stay blocked, not guessed.

A bulk workflow is ready when one rejected row can be explained and one accepted row can be reversed safely—not when a spreadsheet merely opens without mojibake.

## Frequently asked questions

Does Naasher currently support general CSV import for bulk scheduling?

Naasher does not currently promise a general CSV import contract. Treat CSV as a validated staging and migration artifact unless the current product UI and documentation explicitly expose an importer for your workspace.

Should a CSV store Riyadh local time or UTC?

Store a canonical UTC instant and retain the named source zone such as Asia/Riyadh. Generate both with a time-zone-aware library and show the local interpretation in the dry run.

Can media use a private dashboard URL?

Not if the provider must fetch it directly. Use a time-bounded HTTPS URL that remains reachable for the full processing window, or upload through the product's supported media flow.
