i like what the tool offers but i wish I didn't need to keep the sidebar open to refresh the data
25 janvier 2026
Réponse de Market Data
Thank you for the feedback. We're glad to hear you like what the tool offers. The need to keep the sidebar open is a limitation of how Google Sheets add-ons are allowed to refresh data, but we understand how inconvenient that can be and are always looking for ways to improve the experience within those constraints. We appreciate you sharing this and hope the tool continues to be useful for your workflow.
Excellent..

Works well
Works well. would like to see refresh of selected cells only, rather than all the 400+ in my sheet.

Réponse de Market Data
Thank you for the review! We're glad to hear the tool is working well for you. Your point about refreshing only selected cells makes a lot of sense, especially on larger sheets where a full refresh can be inefficient. Feedback like this is very helpful as we continue improving the Sheets experience, and we appreciate you taking the time to share it.
The google method for downloading…
The google method for downloading minutes is efficient. But... there are always gaps in the minutes when I run a backtest on the data.

Réponse de Market Data
Thank you for the feedback! We're glad to hear the Google Finance method for downloading minute data has been efficient for your workflow. We also appreciate you pointing out the gaps you've encountered during backtesting—those kinds of observations are very helpful. If you’re able to share specific symbols and date ranges through a support ticket, our team would be happy to investigate and correct any underlying data issues.
Very customer focused
Very customer focused. They immediately sent me a welcome email and reached out to make sure I understood how to use the product and that they were open to enhancement requests.
Google Sheets functionality works great.

I think you have a wonderful product
I think you have a wonderful product. I received a letter talking about future expansions of the tools to include greeks for options that have already traded and do not exist anymore. However, I think you should license your function to Google Workspace and Google One. Meaning, Google pays you for a license for the use of your add on and it would be included with the users Google One or Workspace accounts. I think you would make a lot more money, and you could hire more people. There's that. What I am saying is, think bigger.

Réponse de Market Data
Thank you for the thoughtful review and the kind words about the product. We're glad you're enjoying it. The idea you mentioned about licensing the functionality through Google Workspace or Google One is an interesting perspective, and we appreciate you taking the time to share it. Feedback like this helps us think about different ways the product could evolve as we continue expanding features—such as the planned historical Greeks support you referenced. Thanks again for the encouragement and for using Market Data!
No near realtime options data in…
i need help to fix the spreadsheet extensions. i understand that I only have near-realtime options data. please help
I am a new user. I signed up for $144/year subscription. I want to plan my options trading and need realtime options pricing data. for the most part your google sheets extension fails. please help me
=OPTIONDATA(R4,"ask") gives me ?NAME error - where R4 is AAPL
=IF(Y4="",0,OPTIONDATA(Y4,"ask")) gives me ?NAME? error where Y4 is contractid
it works occassionally!
24 décembre 2025
Réponse de Market Data
Thank you for the clarification—and we’re very sorry for the confusion. Your current subscription includes 15-minute delayed options data, not real-time data. That’s why you’re not seeing live prices in your formulas. If you need real-time options quotes, we do offer that on a higher-tier plan.
The #NAME? error you're encountering typically indicates that the Google Sheets extension isn't fully installed or authorized. Since the formula works occasionally, it's likely a setup issue rather than a service failure. Our support team has your helpdesk ticket open and will walk you through correcting it.
Once properly configured, you’ll get consistent delayed options data as included in your plan.
Would you like help upgrading to real-time access, or should we focus on fixing the Sheets integration first?

Very good customer service. Quite happy with the company.

It's fine, but a ton of room for improvement
It works but the data is not particularly fast, needing to run the sidebar to receive quotes is a bit annoying, no automatic refresh intervals, and no support for international securities.

Excellent provider
Great API, excellent data source, and outstanding, very fast support!

WONDERFUL EXPERIENCE
Title: Precision, Depth, and Reliability — A Game-Changer for Our Data Needs
Review:
We've been incredibly impressed with our experience using MarketData. The level of detail and historical depth in the data has been nothing short of exceptional. For our use case—where precision, cadence, and continuity matter—the platform delivered exactly what we needed.
What stood out most was the consistency and clarity of the data. Whether we were pulling historical open interest, volume, or minute-level aggregates, the results were clean, reliable, and easy to integrate into our analytical workflows. The API structure is intuitive, and the documentation made onboarding seamless.
MarketData has become a cornerstone of our diagnostic overlays and rhythm-aware dashboards. It’s rare to find a data provider that balances granularity with accessibility so well. We’re grateful for the transparency, the responsiveness of the platform, and the sense that this tool was built with serious analysts in mind.
Highly recommended for anyone who values data integrity, historical reach, and technical elegance.

Marketdata excellent data provider
Marketdata is very good providing much needed data for a an affordable price. I believe there is still ongoing work with API's and bringing more data points on the way but it is definitely a great start and having OHLCV and OPRA data available at this price point is great. Keep up the good work. Their customer service is also impeccable, any request via tickets is answered within the hour.

Valuable service
Valuable service. I appreciate the google sheets integration. I get a lot of errors and have to refresh the sheet often to keep it working. Better than having to track manually but would appreciate a more stable feed.
25 septembre 2025
Réponse de Market Data
Thank you for your honest review. We're glad to hear the Google Sheets integration has been valuable and helped simplify your workflow. That said, we completely understand how frustrating frequent errors and the need to manually refresh can be. We're actively working on improving the stability and responsiveness of the feed, and your feedback is an important part of that process. If you ever experience specific issues, feel free to send in a support ticket—we’re here to help!
An impressive data service provider

Install was easy
Install was easy, working very well. Quotes are bit delayed, but it is clearly mentioned.

Réponse de Market Data
Thank you for the feedback! We're glad to hear the install went smoothly and the tool is working well for you. You're absolutely right—while the base tier includes delayed quotes, we do offer real-time data upgrades on higher-tier plans for those who need it. If you're interested in switching to a plan with live quotes, feel free to reach out—our team is happy to help!
Some wrong data
In general, I like this service a lot but there is a number of issues. There are duplicate days in 2019, 2021, 2022, and 2023 that aren't trading days, so it makes it difficult to line up with Google Finance (which is what the extension is modeled after). There is also data that is wrong for 2008, 2009, and 2010 and has to be manually corrected.
Overall they have been responsive to correct errors in the past, but these errors persist. If the data was more reliable, it would be 5 stars from me
