FME Form

Hi everyone,I’m currently facing an issue with CSV FeatureWriter transformer writing in a ZIP folder. We recently migrated from FME Workbench 2020 to 2025 and the behaviour of the writer changed in between.2020: when writing a CSV in a ZIP folder, the entire ZIP folder would be overwritten. Meaning that if it contained several files, only the newly written CSV would remain. 2025: when writing a CSV in a ZIP folder, only the specified CSV file in the folder is overwritten. Meaning that all the other files are still existing. I get the same result with FME2024.1.3.Main question here: Which FME version has the correct behaviour ? Case 1 or case 2?If it’s case 2, then it means that I will have to update all the workspaces in my infrastructure that are writing files in a ZIP folder, leading to a lot of extra work → I probably need to clean up the ZIP folder upstream through a SystemCaller or PythonCaller. Have you other options in mind?Please find enclosed a folder with relevant resources:s

Hi,I’m using an API (https://docs.transpoco.net/?version=latest#52611862-77b1-4fe6-8a1d-67fc4904cb54) and need to send a post request for authentication. The issue is that the post request takes the username and passwork on the body of the request as a JSON. Any ideas of how I can create a webconnection to run this request in a way i can safely store the credentials on the webconnection instead of on the httpCaller transformer?  

Hi all,I’m validating polygons (DB tables) and currently using GeometryValidator and SpikeRemover in FME. I’m looking for a short, repeatable workflow that reliably flags:Self‑intersections / bow‑ties Holes outside shell / overlaps / tiny slivers Degenerate parts / zero‑area rings Duplicate vertices/nodesQuestions:Which transformers & order do you recommend for detect only polygon checks? Any tips on tolerances (min area/angle) that avoid false positives when paired with SpikeRemover?If you have a small sample workspace or parameter hints, I’d really appreciate it. Thanks!Sahan

Hi,I have a strange issue when writing to excel. I have a feature writer to excel in dynamic mode. To prevent numbers being converted to a scientific notation I added a Excel Styler where I set the custom numer format to 0. This works perfect.The problem is that now my dates and datetimes are suddenly shown as number. When I change the cell format to date it shows the date, but I want it to directly show the date. When I remove the ExcelStyler, dates are shown as dates. Anyone any idea how to fix this?I use FME 2023.2.5.

Hello,to simplify/reproduce my problem:  I added a User-Parameter on my Attribute-Remover: Which grants me a choice to select which to ignore, but (same as here Attribute Remover does not work with User Parameter | Community 8 years ago) it only removes the values and not the attributes, so when I write it into my database or even a new excel, it creates unneeded columns.Manually selecting attributes in the Attribute-Remover works fine, this only happens when using user parameter. Am I missing something or is there another way?P.S. I also tried AttributeKeeper with User-Parameter, but then they’re unexposed, so I would have to iterate via AttibuteExploder, which simply seems unnecessary complicated...

I am trying to get the labels in this map to offset so that they “print” on their lines (two different labels, one is for pipes and the other one is for manholes).Manholes - is the label like 71100144 - the first row of this label should sit perfectly above the line there.The pipes are the values like KM_… - this one should offset entirely to sit on top of the pipe lines.I hope that makes sense.Is there an attribute I can set? I am using AtributeCreator + TextAdder + PDFStyler.Thanks a lot! 

I have a network of connected points and lines, and I’m looking for a way to create a selection set of points along the network, the key being I want to only select every other point. I tried modular selection counts (odd vs even numbering), network topology build for start and end node, but I can’t seem to get the results I’m looking for. Below is a screen capture - I want to eliminate the grey colored points in between. At intersections these points would be retained if necessary according to the ordering.  Select all points in Orange, skip points in Grey 

What happened to the reader and writer drop down menus in FME 2025.2? Why would they remove them? Am I just missing how to add them back in? So frustrating.

I have some columns within my Excel template that have a lot of text, so I thought to put the wrap text feature on for basically the whole spreadsheet. Thing is, only some of the cells wrap text instead of all of the cells. In the screenshot you can see what I mean - I have tried everything to try and fix this. Hoping someone in this community can assist! I tried using the ExcelStyler transformer too to no avail. 

I have an AGOL feature layer with a DateOnly field that I am trying to filter out the last 365 days worth of data. Is there an easy way to complete this?The data is formatted in the following way:2021-01-01

i have many PDF , that PDF i want to merge in single PDF  how can i do this 

The zoom slider bar is missing in FME Flow 2026.1. Please bring it back. It makes zooming more convenient. It was in FME Desktop 2021. Are there plans to bring it back? Or is there identical functionality in FME Form 2026.1? If so, where?

Hi, is there any way to see the full request that was sent by OpenAPICaller? I struggle with a PUT request to api.avima.app and the Avima support team would like to se my full request. Thanks 

Hello everybody,I am trying to build a flow app: The user has an Excel file with 3 columns.  the flow app must show the values of theses columns as one parameter (I want to have the chance to filter the list using one of the 3 columns). My Problem is to get the contents of the excel file. If I try it with the User Paramters Window, I can import from dataset or reader formats. But with these options I do not get the contents but the headers or the name of the readers.I can save the contents of the File in a SQL Database. But I do not know how I can read them and show them in the user parameter List. Has anyone any Idea, how I can get a List with a filter to show those values of the excel?Thanks in advance!Manuel

I have a very simple workflow setup:read a table (typically either a .CSV or Excel file) which then connects to an Attribute Manager set up with multiple fields from a template that adds and renames them so they can be seamlessly imported into another database with exactly the same field names; and then this connects to  Excel Writer (the file format required for import)Since the files I’m reading into FME Workbench do not have all the fields or match exactly those in the template/Attribute Manager has (the point of the workflow), I get an “incomplete transformer” error message. The workflow executes flawlessly, however, and I’m getting the results I need.I’m wondering, however, if there is a way to eliminate the error - the red “incomplete transformer” icon in the navigator window is a bit disconcerting. 😉 PS: I have added the following annotation to the AttributeManager should there be no way to get rid of the error message/icon before I share the workflow.************ATTRIBUTE MANA

Just sharing information about a new feature I found."Enable Performance Profiling" would be introduced in FME 2025.2 Workbench. You will be able to log detailed performance profiling on workspace run easily whithout editing header.Have been waiting for 10+ years :-)Sharing: Detailed Profiling of Workspace Running Performance[Addition] The command is available since FME 2025.1. I have overlooked that... 

Unfortunately FME 2025 for Mac Silicon is still missing some file format integrations. What is the roadmap to get a complete collection of formats on the ARM plattform?I have had to resort to running an Intel version of FME on my Mac in order to be able to read File GDB and 2DPDF. (I don’t get to choose my source formats...). But it would be great to utilize the machines full potential, after all it was many years since Mac had an Intel in their line up.Previous discussion on the subject with more missing formats mentioned: 

I’m testing the new OPENFILEGDB Reader in 2026.1 that supersedes the old Open GDB Reader, but it doesn’t resolve my subtypes and domains. Am I missing something?If not, please bring this functionality back, as it is/was one of the main reasons for using the Open Reader.Workaround for now: the old one is still present albeit marked as deprecated, so I guess it may disappear in the near futureOld Open GDB ReaderNew Open GDB Reader 

All I want to do is create a TIN from a point CSV. I have used the TINGenerator transformer, but the TIN that is created does not have any elevation. The geometry is 3D in the Inspector, but it does not show any height information. If I create a TIN in ArcGIS, it has the correct elevation. I will also post my workflow. Can anyone help me?  

Hi All,Has anyone experienced issues with the AutodeskDocsConnector transformer when downloading Revit files from Autodesk Construction Cloud (ACC)?In my case, when the Revit files are downloaded via the transformer as part of an automation, the resulting files are noticeably larger in size and FME is unable to recognise them as valid Revit files, returning an error. However, when I download the same Revit files manually from ACC, the file size is smaller and the files are read correctly in FME without any issues.I would appreciate any insights or similar experiences, as well as suggestions on what might be causing this discrepancy.I’m using FME(R) 2024.2.4.0 (20250318 - Build 24831 - WIN64)Thanks :)

Hallo everyone,I copied and upgraded an ArcGIS Dimension Feature Class (File GDB) using ArcPy.However, when trying to read it in FME 2024 (FeatureReader / File Geodatabase Reader), I get this error:Unable to convert row to 'DimensionFeature'FME can see the schema, but fails when reading the features.Does FME support reading Dimension Feature Classes, or is there a known workaround?Thanks.

We’re currently in the process of looking to move to a newer version of FME Form (2025.2) but we’ve hit an issue where we can’t meet the required dependencies for adding a Smallworld reader regardless of having the correct files in the right locations. If we open an older workspace with the reader already added, it will still complain about missing dependencies but the workspace will execute correctly.If you select ‘Update Reader’ from the navigator you can add additional feature types etc and change parameters, but you can’t add a new reader due to the missing dependencies. I noted that there was a Fix in Build 25811, but when I tested in 2025.1 (before the fix), there are no issues adding a Smallworld reader. I understand that the Smallworld user group probably isn’t the largest but is anyone else having the same issue. Would really appreciate if someone is able to provide a sanity check. Thanks

I have a COG with a scale factor (excerpt from GDALInfo)Band 1 Block=1024x1024 Type=Int32, ColorInterp=Gray  Min=-50313.000 Max=57304.000  Minimum=-50313.000, Maximum=57304.000, Mean=4745.177, StdDev=7550.452  NoData Value=-32767  Offset: 0,   Scale:0.1How do I apply this scale factor in FME?   If I clip the input and create a new tif,  the scale factor is dropped and the values are 10 times the expected.In this particular case I can just scale the value back down, but in general, is there a way to retrieve the scale factor and apply it? 

Hi I am using the OpenAIChatGPTConnecter in FME Form and entered all relevant details but receiving this error- Could not resolve hostname Obviously something network related, any further ideas? I cannot ping to the endpoint from command prompt.

I’m trying to follow the FME Form course from a MAC and one of the very first exercises is using a Esri Geodatabase (File Geodb Open API) writer. Unfortunately I’m getting this error on the platform. Is there any workaround for this?
