I’m struggling with updating Google Sheets using the Go client library for Sheets API V4. I have a two-dimensional string slice ([][]string) that represents my table data with three columns, and I need to write this information to a spreadsheet.
I successfully completed the quickstart tutorial for reading data from sheets, which works perfectly. However, I can’t find any clear examples showing how to perform write operations. The official Go client library documentation seems overwhelming and hard to understand for someone new to this API.
I’ve been searching online but haven’t found any straightforward Go examples that demonstrate writing or updating sheet data. There are examples in other languages, but I specifically need help with the Go implementation.
Can someone provide a simple example of how to write a multi-column table to Google Sheets using Go and the V4 API?
API boilerplate and auth setup is such a pain. I used to waste hours fighting with Google’s client libraries and scope configs.
I ditched writing all that Go code for auth, data conversion, and error handling. Now I just use a simple Latenode automation that connects straight to Google Sheets - no complexity.
Trigger it with a webhook from your Go app and send JSON data. No converting to [][]interface{} or dealing with ValueRange objects. The automation handles all the Google API stuff.
I run this for several data export features in our apps. Way cleaner than maintaining sheets API code in the main codebase.
had the same issue last month. use srv.Spreadsheets.Values.Append() instead of update when adding new rows. make sure you set insertDataOption to “INSERT_ROWS” or it’ll overwrite your existing data. also watch your range format - i kept screwing up the sheet name syntax.
When working with the Go Sheets API, I faced similar challenges. It’s crucial to transform your [][]string data into [][]interface{} before using BatchUpdate. Start by defining a ValueRange that includes your target range in the spreadsheet. For updating or writing data, utilize spreadsheets.values.update for individual ranges or spreadsheets.values.batchUpdate for a batch of ranges. Make sure you understand the ValueInputOption, which determines if the entries are interpreted as RAW or USER_ENTERED, affecting formula processing. Also, be mindful of your OAuth scopes; the permission for reading differs from writing, which can often lead to confusion in the setup.
Use srv.Spreadsheets.Values.Update() where srv is your sheets service client. Took me hours to figure this out when I started. You’ll need to convert your [][]string to [][]interface{} by looping through each row and casting the strings. Create a sheets.ValueRange object with your data and specify the range like “Sheet1!A1:C10”. Set the ValueInputOption to “RAW” or “USER_ENTERED” depending on whether you want formulas processed. Also, make sure your auth scope includes write permissions - this tripped me up since the quickstart only uses read scope.
