Smartsheet to Databricks: How to Move Your Data
Move Smartsheet into Databricks with Airbyte. Why every column but dates arrives as a string, the header naming rule, and building a bronze and silver layer.
Moving Smartsheet into Databricks takes data that a person maintains by hand and puts it where Spark can reach it. That is genuinely valuable, because the sheet somebody updates every Friday is often the only place a piece of business context exists.
This guide covers the managed path with Airbyte. Two connector behaviours shape the work, and both come from the fact that a spreadsheet is not a database: almost every column arrives as a string, and column headers are an interface that a well-meaning edit can break.

Why move data from Smartsheet to Databricks?
Two situations account for most of these pipelines.
The first is joining hand-maintained context to system data. Project budgets, account tiers, territory owners, a list of strategic customers. These live in Smartsheet because a person curates them, and they are exactly what your lakehouse tables lack.
The second is history. Smartsheet shows the sheet as it is now, and a lakehouse can hold what it looked like every week for two years, which is how you answer questions about how a plan changed. If you only need current contents for one dashboard, a Smartsheet report is simpler.
What do you need before you start?
The setup is short, and one item is a conversation rather than a credential:
An API access token. Generated from the account menu under apps and integrations, needing only read access on the sheets in question. The same token can be reused across every source you create.
The sheet ID, which is not in the URL. Unlike Google Sheets, you find it inside the Smartsheet app under File and then Properties. This catches everyone at least once.
One source per sheet. A source instance syncs one sheet, so replicating twelve sheets means twelve sources. They all draw on the same limit of 300 requests per minute per token, which is generous given the connector makes only a handful of calls per sync.
An agreement about column headers. Headers must contain only alphanumeric characters and underscores, so a rename from status to Status (Q3) breaks the stream. Tell whoever owns the sheet that headers are an interface, and consider a protected header row if your plan supports it.
On the Databricks side each stream becomes a table in Unity Catalog and the connector needs permission to create Volumes for Avro staging. Agree the catalog and schema before the first sync.
How do you build a Smartsheet to Databricks pipeline in Airbyte?
Step 1: Agree the rules with the sheet owner
Explain that column headers are now an interface and that a rename breaks the sync. Ask what the columns are supposed to contain, because you will need that to write the casting layer, and hand-maintained data always has a few columns whose intent is not obvious from their contents.
Step 2: Configure the Smartsheet source
Click Sources in the left navigation, then New Source, and select Smartsheet, following adding a source. Supply the access token and the sheet ID. While you are here, name the sheet-level and row-level metadata fields you want, because they are available but not included by default. Row metadata is usually worth taking, since it answers when a row last changed.
Step 3: Configure the Databricks destination
Click Destinations, then New Destination, and select Databricks, following adding a destination. Supply your workspace details, the catalog and schema, and authentication. A Smartsheet is thousands of rows rather than millions, so volume is never the constraint on this pipeline.
Step 4: Create the connection and choose a sync mode
Click Connections, then New connection, and choose a sync mode. Incremental with deduplication suits a sheet with a stable row identifier. Full refresh overwrite is reasonable on a small sheet. Full refresh append is the option worth considering if anyone wants history, since it accumulates a snapshot per sync.
That last option is the one people overlook. On a sheet somebody edits weekly, a daily snapshot gives you a change history the source does not keep, at almost no cost given the volume.
Why does everything arrive as a string?
Because only date and datetime columns get real types. Everything else, including Smartsheet's richer column types such as contacts, checkboxes and dropdowns, is treated as a string during schema generation. The table you land is therefore not the table anyone should query.
Build a modelled table over the raw one that casts each column to what it actually is, and make that layer fail loudly when a cast fails. Hand-maintained data contains typos, and a numeric column with the word approx typed into one cell will silently become null in a permissive cast and a visible error in a strict one. You want the error, because the person who typed it can fix it in ten seconds.
Databricks makes this comfortable. Treat the landed table as bronze and the cast table as silver, choosing per column whether a bad value should become null or break the build. A budget figure deserves the strict treatment; a free-text note does not.
What happens when someone edits a header?
Column headers must contain only alphanumeric characters and underscores, which is a constraint of the Airbyte protocol rather than of Smartsheet. Smartsheet itself is happy to let someone write Status (Q3 revised), and that is when the stream stops working.
The awkward part is that a person renaming a column is doing something entirely reasonable from their point of view. They are tidying a spreadsheet they own. Nothing in Smartsheet suggests the header is load-bearing, which is why the conversation in step 1 matters more than any configuration.
Add a freshness check on the destination table so a stalled sync surfaces within a day rather than when someone notices the numbers look old. On any pipeline whose upstream is a person, that check is worth having regardless of how carefully you explained things.
Frequently asked questions
Why are my numeric columns strings?
The connector types only date and datetime columns. Everything else is generated as a string, so cast it in a downstream table choosing per column how bad values should behave.
Can one Smartsheet source sync several sheets?
No. Each source instance handles one sheet. Create one source per sheet and reuse the same API access token across all of them.
Where do I find the sheet ID?
Inside the Smartsheet app under File and then Properties. Unlike Google Sheets, it does not appear in the browser URL.
My sync broke after someone renamed a column. Why?
Column headers must contain only alphanumeric characters and underscores. Spaces, brackets and punctuation in a header will break the stream.
Can I do this without writing code?
The Airbyte setup is entirely UI-driven. You will want a Spark or SQL model casting the string columns, which is the difference between a usable dataset and a raw one.
Get your Smartsheet data into Databricks
The technical work here is small and the social work is not. Cast the strings in a silver table, take the row metadata, consider append mode so you accumulate a history the sheet does not keep, and have the conversation about headers before someone renames one.
Airbyte's connector catalog includes 600+ pre-built connectors, so hand-maintained context can sit alongside your system data. For the same source feeding a warehouse, see Smartsheet to BigQuery, and for another source whose upstream is a person, Airtable to BigQuery.
Integrate with 700+ apps using Airbyte
Move data from 700+ sources into warehouses, lakes, and beyond. Set up pipelines in minutes with pre-built connectors and the Connector Builder.
