Comprehensive Guide to Echodata Export Formats: CSV, TXT, and CRM Integration Differences (with KK-DATA Practical Guide)

In daily B2B outbound lead generation work, how to efficiently export batch-verified phone numbers directly determines the efficiency of subsequent CRM import and marketing outreach. Many teams spend a lot of time on number screening but fail at the export stage—either due to incorrect format or missing fields, creating data silos. This article will deeply analyze echodata export formats (CSV export, TXT export) and their differences when integrating with CRM systems, combined with KK-DATA’s actual operational workflow, to help you build a complete data pipeline: “Generate → Filter → Export → Import CRM”.

1. What Are the Echodata Export Formats? Common CSV/TXT Field Analysis

The so-called “echodata” generally refers to the tool formats provided by most number screening platforms (such as 007data, thdata, etc.). These platforms usually offer two mainstream export formats to meet different downstream system requirements:

Format	Features	Typical Fields	Use Cases
CSV	Structured row/column data, each row is a record, fields separated by comma (or other delimiter)	phone number, registration status, activity score, gender tag, detection time	Direct import into CRM like Airtable, Salesforce, HubSpot; Excel processing
TXT	Plain text, usually one number per line or simple multi‑column, delimiter not uniform	+8613800138000 (number only) or +8613800138000 1 0 (number + status flags)	API batch push, legacy scripts, low‑end marketing tools

Field Analysis: In CSV, activity score is often a number from 0–100 or an active mark for 7/15/30 days; gender tag is usually recognized from avatars as Male/Female/Unknown; registration status is marked as active/inactive or 1/0. Different CRMs may map these fields differently—for example, HubSpot custom field character length is limited to 25 bytes, and longer tags may be truncated.

2. KK-DATA Export Format Comparison: CSV vs TXT Advantages and Use Cases

KK-DATA also supports CSV and TXT exports, but with significant optimizations in field richness and customizability.

2.1 CSV Export: The First Choice for Structured Data Integration with CRM

CSV is the “gold standard” after export, especially suitable for CRM systems that need to retain multi‑dimensional tags.

• More comprehensive fields: In addition to basic “number, platform, status”, KK-DATA provides tgid (Telegram unique ID), wsid (WhatsApp ID), active days (customizable window, e.g., 7/15/30 days), gender (avatar recognition), dedup warehouse mark (indicates whether the number exists in the platform’s dedup database).
• Customizable export columns: You can check the fields you need before submitting a task, avoiding exporting all fields which may result in oversized files or messy field mapping.
• Activity markers: For example, active_days: 12 indicates the user has interacted within 12 days; CRM can use this value to tag.

Recommended tools: Airtable, HubSpot, Salesforce, Zoho CRM.

2.2 TXT Export: Quick Batch Calls and Legacy System Compatibility

The biggest advantage of TXT export is small file size and minimal format, suitable for rapid batch operations.

• Only number text: One full international number per line (e.g., +8613800138000), no metadata.
• Legacy system compatibility: Many older marketing tools or APIs only accept plain text number lists and cannot parse CSV structures.
• Batch call scripts: You can directly use cat users.txt | xargs curl in a shell script for batch sending.

Note: Since activity, gender, and other metadata are lost, it is recommended to filter out invalid or inactive numbers during the KK-DATA screening stage before TXT export. The resulting TXT will be “clean” for subsequent calls.

3. Detailed Differences Between Echodata Export Results and KK-DATA (Features, Billing, Experience)

Objectively comparing echodata‑like platforms (007data, thdata) with KK-DATA, there are several key differences in the export stage:

Comparison Dimension	Echodata‑like Platforms (General)	KK-DATA
Field Customization	Usually exports all fixed fields, cannot choose	Supports checking needed columns before task submission
Unique ID Export	Most only export phone numbers	Supports exporting platform unique IDs like tgid, wsid, convenient for cross‑system reconciliation
Dedup Marking	Need to deduplicate manually after export	Built‑in “Data Dedup Warehouse”, automatically marks duplicates upon export
Export Speed	Exporting millions of records may take a long time	Immediate download after task completion; single task up to ~1 million records
Billing Model	Plan‑based (monthly/yearly)	Pay‑per‑record (no subscription), pay as you use, see Billing Page

Note: The unit price you see on other platforms may differ from KK-DATA, but this article does not compare specific figures. Please refer to each platform’s real‑time prices.

4. Complete Workflow from Number Screening Export to CRM Import (Step‑by‑Step Guide)

Below we use KK-DATA as an example to demonstrate a complete five‑step process: “Generate → Screen → Export → Clean → Import CRM”.

4.1 Step 1: Create a Screening Task in KK-DATA and Set Export Fields

1. Log in to the App Console.
2. Click “New Screening Task”, select the target platform (Telegram, WhatsApp, iMessage, etc.) and detection types (active/valid, activity, gender recognition).
3. In the “Export Settings” module, check the fields you need: e.g., phone number, tgid, active days, gender, detection time.
4. Submit the task; the system will display the estimated cost.

4.2 Step 2: Export CSV and Eliminate Duplicates Using the Dedup Warehouse

1. After task completion, go to the “Task Details” page and click “Download CSV”.
2. The exported CSV contains a dedup warehouse marker column (e.g., is_duplicate: true/false).
3. In Excel or Python, filter out duplicate data based on the marker to ensure the same customer is not imported multiple times into the CRM.

4.3 Step 3: Import CSV into CRM (Using HubSpot as an Example)

1. Open HubSpot, navigate to “Contacts” → “Import” → “Import from file”.
2. Select your downloaded CSV file.
3. In the field mapping step:
   • phone number → map to HubSpot built‑in Phone field.
   • active days → map to a custom number field active days.
   • gender → map to a single‑select dropdown field gender.
   • Ignore unnecessary fields like is_duplicate.
4. Check international number format: Ensure numbers in CSV are in +86 13800138000 format, not 8613800138000 or 13800138000. HubSpot automatically parses the E.164 standard starting with +.
5. Handle missing values: If gender is Unknown, you can set the import rule to empty or “Not filled”.

5. Export Format Best Practices and Common Pitfalls

In practice, the following details are often overlooked, leading to data integration failures:

• Field compatibility: Check whether your target CRM supports all custom fields you export. For example, Salesforce has character limits (usually 40 characters) for custom field names.
• Encoding selection: As mentioned, UTF‑8 with BOM is the universal recommendation for CRM imports. If fields appear garbled after export, check this first.
• Large file splitting: CSV files with more than 100,000 rows may freeze in Excel. It is recommended to use the “Data Dedup Warehouse” in KK-DATA to process in separate tasks, or split the file into chunks of 50,000 rows each using Python after export.
• Number format consistency: Numbers in screening results may contain spaces or dashes (e.g., +86 138-0013-8000). They must be unified into E.164 format (+8613800138000) before CRM import. You can clean them in Excel with the formula =SUBSTITUTE(SUBSTITUTE(A1," ",""),"-","").
• Privacy compliance: If numbers involve sensitive countries (e.g., EU numbers under GDPR), ensure you have a lawful basis for processing to avoid data violation risks.

6. Export Experience Improvements When Switching from Echodata Users to KK-DATA

If you previously used echodata (or 007data, thdata) type platforms, switching to KK-DATA may bring the following direct improvements in the export stage:

• Faster export speed: KK-DATA supports immediate download after task completion; millions of records can usually be exported within minutes. Some platforms require waiting for “packaging processing”.
• Customizable fields: No need to export all fields, reducing file size and subsequent processing workload.
• Real‑time cost preview: You can see the estimated deduction before submitting a task, avoiding overspending.
• Integrated dedup warehouse: Cross‑task dedup is built‑in, saving the time of writing manual dedup scripts.

These differences do not mean other platforms are bad, but for teams with a “pay‑per‑record, pay‑as‑you‑go” need, KK-DATA feels lighter in certain details. Feel free to log in to the App Console and test it yourself.

Frequently Asked Questions

Q: Are the CSV field structures of Echodata and KK-DATA the same?
A: Basic fields are similar (number, platform, status), but KK-DATA additionally provides fields like tgid, wsid, active days (customizable window), and supports selecting export columns. For specific fields, refer to the Documentation.

Q: How to retain activity information after TXT export?
A: TXT only retains number text; no fields can be attached. If you need to keep activity, export CSV and use formula columns (e.g., in Excel =IF(B2>7, "Active", "Inactive")) to mark.

Q: Which exports faster, Echodata or KK-DATA?
A: Speed depends on data volume, network latency, and server load. KK-DATA supports immediate download after task completion, with a maximum of ~1 million records per task; export time is usually within minutes. Actual experience depends on the console.

Q: Can exported numbers be directly used for WhatsApp batch sending?
A: It is recommended to retain only “valid” detection results (export only numbers marked as “valid”) to avoid sending failures or account bans due to invalid numbers. KK-DATA supports filtering out invalid numbers during the screening stage.

Q: Are 007data’s export formats compatible with KK-DATA?
A: Both are standard CSV/TXT, but field names may differ. If merging data, it is recommended to unify field mapping in Excel/Python. Billing models differ significantly—007data usually uses plan pricing, while KK-DATA charges per record. See Billing Page for details.
