To import hundreds of website monitors, start with the destination service’s current import template—not a CSV exported by another provider. Map each monitor to the template’s accepted fields, test a small batch, then compare the created monitors with your source inventory. UptimeRobot documents a dashboard-based bulk upload; Better Stack offers bulk URL entry and an API, while Checkly supports code-managed monitor definitions.
Plan the import before editing a CSV
Make a source-of-truth inventory of the monitors you intend to create. Include each URL or IP address, what it represents, and any settings you need to preserve. Keep this inventory separate from the upload file: the destination’s template determines which columns and values it accepts.
- Remove targets you no longer intend to monitor.
- Identify duplicate URLs or IPs and decide whether they represent distinct checks.
- Note special requirements such as a port check, keyword check, tags, or a particular interval.
- Keep alert routing on your checklist; a monitor import may not configure notifications.
Import monitors with UptimeRobot’s CSV template
UptimeRobot’s Help Center describes a Bulk Upload workflow. In the dashboard, select the plus icon, choose Bulk Upload, download the provided template, fill it in, and upload the completed file. Use the template currently offered in your account if its headers or accepted values differ from descriptions here. UptimeRobot documents the process in its Help Center article, “Optimizing Mass Monitor Management with Bulk Upload Feature” (August 27, 2025).
Map each row to the destination fields
The Help Center identifies URL/IP as the only required attribute and describes these additional fields. It does not make a generic header row a safe substitute for the downloadable template: copy the live template’s exact column names and format.
| Field | How to use it |
|---|---|
| Type | Choose HTTP, Ping, Port, or Keyword. HTTP is the documented default. |
| URL/IP | Enter the target address or IP. This is the only required attribute identified in the Help Center. |
| Interval | Enter the check interval in seconds, using a value accepted by the account and template. |
| Friendly Name | Use a recognizable label, especially when several targets have similar addresses. |
| Keyword Type and Keyword Value | Provide the keyword settings for a Keyword monitor; verify the template’s current accepted values. |
| Port | Provide the port value for a Port monitor. |
| Tags | Separate multiple tags with semicolons, as described by the Help Center. |
Check intervals against your plan
UptimeRobot’s Help Center documents an interval range of 60 to 86,400 seconds. Its migration guide also says the shortest interval available depends on the plan. Check the limits for your account before assigning intervals; do not assume every monitor can use the shortest documented value. UptimeRobot
Test, upload, and reconcile
- Fill a small, representative batch first. Include different monitor types and settings you plan to use, rather than testing only uncomplicated HTTP checks.
- Upload that batch through the dashboard’s Bulk Upload workflow and inspect the resulting monitors. Do not assume the service offers a preview or rollback unless the current interface says so.
- Prepare and upload the remaining rows once the sample matches your intent.
- Compare the created targets and settings with your source inventory. Look for missing or duplicate targets, incorrect names, malformed tags, and settings that did not carry over.
- Check notification or alert routing separately if your service manages it outside the monitor definition.
Convert an export from another monitoring service
Do not upload a source provider’s CSV unchanged unless the destination explicitly supports that format. A CSV is only a container: column names, accepted monitor types, interval units, and optional settings can differ.
UptimeRobot’s Site24x7 migration guide describes a particular path: export Site24x7 monitor configurations as a CSV inside a ZIP, download UptimeRobot’s template, convert the data to match that template, then upload it. Treat this as a vendor-specific example, not a universal mapping. Inspect converted rows before importing and verify the resulting monitors afterward. The guide suggests using an AI tool to reformat an export, but that does not guarantee a correct conversion.
A safe field-mapping process
- Extract the source export and identify its columns and value formats.
- Download the destination’s current template and identify its required fields and allowed values.
- Map only fields with equivalent meanings. For example, do not assume that an interval expressed in minutes can be copied into a field expecting seconds.
- Resolve unsupported source settings deliberately: omit them, configure them separately, or choose another import route rather than silently mis-mapping them.
- Review a small converted sample in the destination before converting the full inventory.
When CSV upload is not the right route
Better Stack: paste URLs or use its API
Better Stack documents bulk entry by pasting URLs one per line, followed by editing monitor configuration before creation. It also offers a Monitors API. This can be simpler when the source is just a URL list or when you want to automate creation, but it is not the same as importing arbitrary vendor CSV columns. Better Stack says: “Please message us at hello@betterstack.com, and we will help you with the transition.” See its bulk importing monitors documentation for the current workflow.

Checkly: manage monitor definitions as code
For teams already managing infrastructure in source control, Checkly describes generating hundreds of monitors from a TypeScript file and deploying through its CLI, REST API, Terraform, or Pulumi. This is a code-based configuration approach rather than a CSV upload. It can fit repeatable, reviewable changes, but requires the team to work with those code and deployment workflows. See Checkly’s documentation for current details.
Troubleshoot common import problems
- Rows are rejected: compare the file with the current destination template. Check exact column names, required URL/IP values, and whether each type-specific field is populated.
- Keyword or port monitors are incomplete: confirm that keyword checks have both keyword type and value, and that port checks include a port, as applicable to the destination’s current template.
- Intervals are unavailable: check the account’s plan limits and the unit expected by the template. UptimeRobot’s documented range is 60–86,400 seconds, but the shortest interval depends on plan.
- Tags appear as one tag or are malformed: UptimeRobot documents semicolons between tags; verify the live template’s current delimiter instructions.
- Converted settings do not match the source: inspect the mapping instead of repeating the upload unchanged. Providers may use different names, units, and supported monitor types.
- Monitors exist but alerts do not behave as expected: check notification configuration separately; do not assume importing a target also imports its alert recipients or routing.
Or skip the browser setup
If you need a page screenshot rather than an ongoing uptime check, ScreenshotNeo is a website screenshot API and MCP server; it does not replace a monitoring service. One GET request returns an image or PDF. For example, this cURL request saves a WebP screenshot of the target URL:
Rank #4
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo API documentation for request options. It accepts cookie or consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each step can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits are not billed, and responses identify the page verdict and billing status in headers. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for AI agents. The Free plan includes 1,000 screenshots a month with no card; paid plans start at $5 for 3,000.
